Don't aim too high, but set yourself a goal which is a little bit out of your reach. You might achieve it and then you can set a new goal.

Success doesn't come overnight and there's certain things you can't do. I've missed so many weddings, christenings and birthdays, but I know all my family are there behind me, wanting me to do really well and it was worth the sacrifice.

Sport teaches you about commitment and to dedicate yourself. Whether you make it to the top or not, sport gives you great skills that you can use in life.

There's no better feeling, even if I've won a race, than recording a personal best. It's setting yourself personal goals, but also realistic goals.

Make sure you eat healthy food. You can have the occasional treat, but you also need to balance your diet with foods such as meat and vegetables. It will prevent you from getting colds and enable you to train and to do whatever you want in every day life.

I've always been fortunate in that I'm quite good at what I do, but there have been many people who have made it to the high level and they weren't necessarily the fastest runner in their class at school. Concentrate on yourself. It's down to planning, preparation and being dedicated.

I'm not always the favourite to win, but I still enjoy it. The main thing is that I've planned for it and even if the result isn't great, I know I've done the best I can do. It's being true to, and believing in, yourself.
