Don't bet on this. If it happens, GREAT! If it doesn't, at least you won't be crushed. Success doesn't always happen the first time around. Sometimes it takes multiple plays before the jackpot lands.
But putting all of this aside, don't do it for money. Money is an important factor but as others have echoed on here, do it because doing what you enjoy/love outweighs what you make. Money is icing on the cake.
