You should always give 100%. If you do that then no-one can ask any more of you. Someone once said to me when I was a kid: 'If you're asked to do ten sprints, by all means do 11 but never do nine because you're only cheating yourself'.
You have to go out onto the pitch feeling good about yourself. That can give you that extra 30 per cent.
When I go home every night, I can look in the mirror and say I have given 110 per cent for Newcastle United. If people aren't happy with that, I can't give any more.
My motto in life is 'if you give 100 per cent then no one can ask any more'.
