A lot of tournaments are on hard courts. Plus now you have to do so much more pounding on your body.
All my career I've really been in the Top 10 barring those lovely injuries, but each one is tough.
All those people that I toured the world with - I got on with them fine, but I suppose only two of them would really count as friends.
But I tell you, there's a ton of stuff that I'd not change at all. I kind of think this year's gonna be good for me.
Did you know that Christmas Day is absolutely the best day to fly? It is. No crowded airports and crowded planes. I always flew to Australia. That's what Christmas was for me - a plane journey to the next tournament.
From the beginning I loved it. Who knows why? It was just everything to me. I couldn't get enough of it. Tennis, tennis, tennis every day.
I always believed in the justice system until then. Not now.
I can be happy, but mostly I'm not. It's just the way I am. I'm working on it. Playing tennis helps.
I can go out to dinner when I want. I can see friends, and I can live, I guess, a normal life. But, gosh how I miss it.
I did realise more than ever, after the stabbing, that tennis is a business - a tough business.
I do think sometimes about how different my life would be without sport.
I don't feel like a victim and I don't want to be regarded as a victim.
I guess you could say that mine has not been a conventional career.
I have this terrible dark side to my personality, which playing tennis keeps at bay.
I just don't want to slip away. I want to go with a fight.
I just want to finish my career on a note I want to finish on.
I know that I wouldn't have put the hard work in if it hadn't been fun.
I mean, I'm not going to come back and play 16 tournaments. My body can't handle that.
I miss being competitive. I miss the whole thing.
I never really did Christmas before. Christmas Day? I mean - what's that? What's it all about? I was always flying on Christmas Day.
I think about when I was a little girl, and he was telling me the scores. Gosh. Life was so much less complicated when I was a child.
I used to pretend that I was Tom attacking Jerry, who was drawn on the ball.
I was so happy. I look back on that time with such happiness. It was never about being a great tennis player or being ambitious. Dad wasn't like that. He was ambitious, but it was just about having fun.
I'd like to play a limited schedule.
I'm hoping that 2006 will be my year. I've given myself until the end of it to return. If I haven't done it by then, I'll retire.
I'm not very good when I'm not playing tennis. The dark side tends to try and take over. I become more and more unhappy, I eat too much, worry too much and get generally very miserable.
I'm still playing regularly and I'm coming back if I can.
I've done loads of research and I think bright colours, music and funny characters are the keys to getting kids attention.
I've had to learn - and this has been hard - that even if you want to go out and play, if your body isn't listening you have to separate the two. I didn't associate the two.
If you are losing so many of the top names - I mean that's what makes tennis exciting when you have those great matches. You need your big names to stay around. You also have to think of younger generation: the longer these players are around, obviously, the better.
In truth, most of the time, I'm not a terribly happy person, I guess.
It all seemed so hard to cope with - all the attention back then. It was new and I was young. I felt so much pressure on me. When I look back, though, I didn't know what pressure was, really. Did I?
It doesn't matter who is playing or how old they are. I just worry about what I can control. It doesn't give me more or less motivation.
It wasn't just the stabbing, it was the fact that my innocence was lost that day.
Little about my career has gone to plan. Little of my life, perhaps.
Madonna has total control over her life, and not many women have that.
Maybe it's being 30, but I'm listening to my body better.
My happiest time was between the ages of six and 10. I would love to have stayed at that age for ever.
One of the reasons why I got so depressed after the stabbing was that I stopped playing tennis.
People think I must have been so talented at an early age, but I don't know - was it talent or hard work? Who knows?
People think I've retired, but I haven't - not at all.
Right now, I'm very fortunate I'm making my living being a professional, and everything else that has happened in my career. But one day it's going to be all taken away, and I'm still going to play tennis because I love it.
Tennis has to become everything to you if you're going to make it to the top. You have to live it.
Tennis is so competitive. I guess that's the way it has to be.
That's one thing when you're not traveling. You have a normal schedule and you can plan Sunday nights.
That's the key to success, isn't it? It has to be fun.
The last few tournaments were brutal. I just don't want to leave with that memory. I don't want to stop that way.
The other players are just waiting to take away your No 1 spot in any way they can.
The thing with a sport like tennis is that you have to train really hard every day, all year round. It makes it easier if you're enjoying it.
The way the game is played you have to be a lot stronger, there's a lot more wear and tear on your muscles.
The WTA has done a great job listening to the players and I think that's important because I'm in the last stages of my career but these girls are in the middle stages.
They're not like normal headaches - it's this pain that makes you think your head will explode. I had to go to bed for days sometimes, just to escape them.
When Wimbledon 's on, you can't get a court. Once it's finished, no one wants to know.
You have to want to play it all day, every day to get to the top.
You know, after the stabbing I didn't do anything for two-and-a-half years; but I think at this stage in my career I can't do that and expect to be back.
You make a few additions to your game and maybe have a few years when you aren't as a good. Like Tiger Woods did a few years back. But you're better off in the long run.
You will never have great tennis champions from England because of the cold and dark, but most of all because people only care about the sport for two weeks a year, and then they're on to something else. There's just not a great love of the sport there.
