I think Serena Williams is the best tennis player of this generation, if not the best ever. It is amazing for her to be playing as well as she is at the age of 31.

You hear a few people saying that, you know, maybe some of the past male players like to watch me play or whatever else, just because I play a bit differently and maybe they can relate to it a bit more with a bigger forehand rather than a backhand, good serve and whatnot.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

Flexibility is crucial to my fitness. Incorporating a good warm-up and cool-down into every sessiondecreases my chances of injury. I use both dynamic and static stretching in my training. I've starting doing a few yoga sessions which incorporates muscle strength and flexibility.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.

You've just got to get over that mental hurdle and those battles in your own head during matches when things aren't going so well. It takes time. It's probably all things I already knew, but for someone to talk about it maybe in a different way makes you realise things.

I think all tennis players have to struggle through the early stages of their career. We start off playing tournaments and really just get by. I always had a dream to play in the big tournaments and never have doubted if it was worth it. Having to battle a little early on in my career makes it all the more worthwhile now.
