good for you tris
actually this attitude is what seperates the top people in most fields from the rest, the actual need or craving for success and the effort they are prepared to put in to achieve it plus often how much effort their parents or partners are prepared to put in to satisfy their craving to see their loved one succeed, others often with less talent can't be bothered to put the effort in, be it extra preperation of car and driver, the applications and presentations to find sponsors or even just deciding to sell which is most important, a fancy road car or a more competative race car. perry mcarthy was the classic example of a driver who gambled everything on financing his desire to be at the highest level, lewis hamilton's father at one point was holding down 3 seperate jobs to finance his sons racing, schumacher would go to his local kart track as often as he could if it was raining just to practice his control in slippy conditions, mcarthy may not have been a champion but he had the need to try and be the best (and was the black stig) lauda came back form his accident in 76 probably a bit too early but he needed to be in that car, similary jonny herbert came back after his F3000 crash into his first F1 drive before he was able to do himself justice just because he had the desire to do it. and there are plenty of cases of drivers who may not have had the greatest natural talent but made themselves great through application and hard work.
it's the same in other worlds, i know of at least one local (to me) footballer who could have been a succesfull professional, he was at a lower league club and acording to their development coach had a lot more talent than another player who went on to play in the premiership but instead this local guy was to concerned with enjoying himself and getting drunk etc, these days he's on the dole. ever wondered why people like richard branson crop up again and again with new businesses? it's the need to make money, to prove they can still do it, peter jones off the dragon's den, made a fortune early in life, lost it and clawed his way back to where he is now and both of them haven't got to where they are now by settling for a 9 - 5 job with a comfortable wage, which doesn't stretch them or their abilities
EDIT: just to add this is why i'm doing what i do and live like i do despite haing an IQ pushing 150, i just can't be bothered and to put it bluntly am lazy and will always opt for the course of least effort / confrontation even if it means i loose.
