I always set out with the intention of winning, usually goes out the window after a couple of sections, because if i didnt then whats the point i might as well save the money and go "practicing". I enjoy the element of competition and "practicing" bores me to tears after 10 mins because it doesnt matter if you cock it up so i find i learn or develop very little a bit like if i enter an event with no personal incentive of winning. To progress i need to "dig deep" sometimes to "pull it back" or "send it". Just me i suppose but thats the way it is with me.
I suppose its about whatever makes you happy and gives you enjoyment. If it was just about being out riding your bike we would all be on worn out uncompetitive bikes with bald tyres and bits held on with bailing wire and tie wraps lol.
