Gliders are not a good compromise. Either an aerotow or a winch launch with the help of a massive V8, then retrieval via all terrain vehicles on the airfield. Done a lot of gliding and a 'green' hobby it is not.
gliding is however a great way to learn flying skills. For me it was gliding, then PPL, then eventually an ATPL and a career on jets. I was extremely lucky though in that the company who employed me as a Flight Engineer decided to train some of us as Pilots. I doubt that route exists now.
However some have got into the game by paying for a frozen ATPL then joining a small airline in a ground ops position. Occasionally you will be noticed by the right people and be given your first chance.
Best of luck whatever you choose.
Kind regards
