If you are young and have no commitments then go for it and see if it is the life that you want to lead. If it turns out not to be then you can always do something else, and you will still have benefitted from the experience.
If you have others depending on you then think it through carefully as the process can be expensive and completely absorbing.
As mentioned, the military is a reasonable option, so long as you can bear all the other aspects of such a life (its not just about flying). Of course you have to meet the grade when it comes to applying, and stay on the pretty steep learning curve as you go through training, but it is an opportunity to be paid for realising your dream.
If you go for the purely civilian option, then throw yourself into it completely. Look for any and every way to get involved in aviation, doing any job that gets you closer to the industry. It shows commitment (a valuable attribute) and you will be amazed at how much you will learn from those around you about the industry. IMHO, that is the way to get ahead in this game.
Good luck!
