Thats good advice Widowmaker. Take an intro flight and see how it fits. It is very different from flying on a computer. 
  
But there is the other side of that coin too! You might get bit by the bug and crave more more more. Thats what happened to me back in 1987 when I was 17 and I did whatever it took to make more money to buy more flight lessons. I would move furniture for $10 per hour (alot for a high school student back then!) and break my balls for more lessons. 
  
 I was crazy for it. I remember that I soloed at 10 hours and after that happened I was allowed to take the aircraft alone to practice. Well, being the 17 year old that I was I had my friend hide in the weeds at the end of the runway one morning at 7:00 am before anyone was even working at the airport. I did my runup and he ran out and jumped in the plane and off we went. Who was more nuts....me or him?!?!? We flew around buzzing lakes and pretending to strafe trains ala WW2 guncamera footage. Landed 45 minutes later and out he jumped into the weeds again. We were just in love with flying.
