you need to find a field and some help is all, with a little instruction you will be surprised how easy it is to fly a glow trainer.
I would not recommend going it alone you are setting yourself up for failure and expense mostly expense, when I started flying when I was 14 there were not really any instructors, just a few willing guys to give you a hand sometimes if they felt like it between there own flying come to think of it almost never
I am 43 now and the club training programs that are around now are great, it's almost imposable to fail the sims that are available are a great tool to build confidence and they have a ton of planes to fly, isn't xmas close by I would put that one on my list .
