Start playing in AM Tours, then when you feel confident
and
play in competition then go for your dream, try out for the mini tours so you can get an idea what an pro tour feels like, then you'll see what it's like traveling (on the road) the money$ situation, motels, if this is your goal/dream in life, you well find way to make it happen, try what Jonathan said, it might work or not work for you. everybody has different incomes, life styles. I play on the National Professional Golf Tours and found way to make it$. I'm from Utah so i have to travel there to play the mini tours.
and have fun playing and good luck.
never stop trying.
