Zotan,

You sound like me when I was 16. I did decide to go into flying as a career and am happy I did.
Flying is a great job, but it is a terrible career. What I mean by that is I truly enjoy the flying - the time I spend in the cockpit. However, I am WAY underpaid for what I do (I am a regional jet captain). I could make just as much money doing a lot of blue-collar jobs. You'll find very few companies who treat you like an actual human being in the airlines compared to how my college friends are treated by their non-aviation companies.
I have had my base changed several times in just 3 years, which would require me to either keep moving or commute. Commuting is very stressful, keeps you away from home a lot more, and gets expensive (hotels, airline passes, etc). I'll soon be displaced even further east, making my commute even harder, or requirng me to leave a place I enjoy living in.
All that being said, I am one of the lucky ones to just have to commute. Thousands of pilots have been furloughed (laid off) from their current jobs in the last few years.
As bad as things are right now, I still do not regret my decision on choosing this career. However a lot of my friends have regretted their career choice, and a lot have quit and gone into other lines of work.
Getting into the industry now it is possible you may never make it any further than being a regional jet captain no matter how hard you work, or how good you are at this job. RJ captains who have been at my company for 7 years only make about 68,000 per year, and we are one of the better paid regionals. We typically get 13 days off per month, which may seem like a lot but is not when you are away from home the other 17-18 days.

My advice to you would be to definitely get that PPL, and if flying is something you truly enjoy and want to do, consider it as a career. Go to college, get a degree in something practical (not aviation related) so you have something to fall back on if you change your mind or it doesn't work out. An aviation degree will not help you get a job at an airline and is almost totally worthless. Do not go into this profession if you want to get rich or have an easy job and a lot of days off - those days are unforunately over.

Let me know if you have any other questions!
