I wouldn't be too quick to idolise too many top pro athlete's.
Many train 6-7 days a week , are home schooled and don't have much of a life outside of their sport.
Sure they seem to live the dream with fame and fortune but most are either washed up or the body has given up by the time they are 30. With most of us living past 80 that leaves alot of life left to survive outside of the sport. ( I am talking about most sport's here. )
For every x pro you see on tv doing well in business/commentry/coaching etc I bet there are 10-20-30 that have fallen on hard times. You just don't hear about them.
It is fine to have hero's but most people will not/can not get to the level of them.
A good grounding in life from a young age is better for all of us.
Go to school , play sport , make lots of friends and if the planets align and you have the necessary skills you may make it in your chosen sport.
Just remember that all teenagers think that their parents are wrong.
It's not untill you reach 30+ that you realise they may have been right.
