Congrats for wanting to go pro. I've though about it too at times but for the time being I want to play more hands, learn the game more, make mistakes, build a bankroll and learn more about myself.
Once I have played 100k-1M hands, am confident with my play, show a nice win, learn from my mistakes, build a appropraite roll for the limit I am playing and understand how playing for a living will affect my emotional, psychological and financial state when I run bad, I may think about playing for a living.
This is one of QTip's great posts:

In case it does not show the title is "To the New, Aspiring Player" post #3812872. The post is in the Limit HE Micro Stakes but is still relevant to all limits and all forms of poker.
In your case, my advice would be to keep playing, practicing, studying and weigh the advantages and disadvantages of making the move with the fact that you should keep family as a #1!
