This is the default reply, and almost always the correct one. It's not at all difficult to be in the top 1% of all players when you figure that 'all players' includes a vast number of recreational players who don't even care if they're winners, and a whole lot more whose knowledge of the game is all from play and none from study. Still, if you can swing a job and poker as a part time thing, that's preferable for most people.

However, if you've got a good savings, have a good winrate over a lot of hands, and won't be inconvenienced by going without an alternate income for 3 months, 6 months, or whatever (i.e. it won't be harder to find another job; you have both an ample bankroll and plenty of money to live on), there's no reason not to take a shot and at least prove one way or another that you could or couldn't do it full-time.
