The only advice I could give is to stay positive and focused in terms of what your goals are, and stick to them. If you can't attain those goals, maybe they're not realistic. At this level only a small percentage of players make it, so you've really got to strive to get what you want.

We have nutritionists to advise us on what to eat, in terms of our protein and carbohydrate intake. It's really important that you get a good balance.

You've got to be committed. It comes down to setting yourself goals as an individual. In rugby you have team goals that you strive for, but you also set yourself simple goals that are achievable. It helps to write them down so you understand what you need to do, and what your focus is. Put them on your wall, then each time you wake up, you'll see them. Then you can just tick them off once you've achieved them.

Always have a plan B and C, because if it doesn't work out there are other things you can focus on. It's important to have a balance to your life, regardless of what you're doing. I've been playing at this level for a long time, but I've got interests outside of rugby, like my family and my children. They keep me sane.

My father's a keen sportsman, and so is my mother. My mother's brothers all played international rugby for Samoa. That's where I got my dreams from.

Everybody reacts differently. For me defeat lingers around for different time periods. I can dwell on some for five minutes or sometimes I can still be thinking about it a week later. It all comes down to experience. You need to reflect on your mistakes and move on. Luckily you always get the opportunity to turn things around in your next performance.

One of the highlights of my career was playing first class rugby for my province, which was Wellington. Another highlight was playing first class rugby with my brothers. Not many brothers get to do that. I can't explain what it felt like to be out there, playing with them. It was a great feeling.
