Thats a great attitude- even if i did think i was really good at it ( which i dont) i cant imagine the stress that would come with doing it knowing i need winners to pay a mortgage,bills etc etc... the fun would go out of it then knowing i need atleast a winner a day or more.. Maybe if i was single still living at home with no daughter and partner i could give it a go but no way when i have to afford so many other things...
If you are good enough (and that is the whole key) the stress isn't much of an issue.
Also not to overdo it. Take time to unwind. Eat right, enough exercise, sunshine etc.
