You need a goal, and to get to that goal you need a plan.
Your plan needs to be pointed at something you will be happy doing for the rest of your working life, and a job that will exist in 10, 20, 30 years.
A qualification of some value will help you get to your target, and it will also let you find out if you actually like what you might be doing.
Take me for example; when I left I went to uni and picked up a couple of degrees in IT/IS, all the rage back then, far king good money, and destined to be the future. I was good at the learning part, I even came up with a couple of software widgets that many people take for granted nowadays, did some expensive consultancy for a couple of banks. BUT, even though I had some nice expensive Austin Reed suits I was not cut out to be the suit wearing type, who sits behind a desk every day........it wore thin very quickly. I much more enjoyed fixing up houses, working with my hands and not dependent on the foibles of other people. I went off to college and got a city and guilds plumbing, advanced plumbing, gas certified, and WRAS certified, did a couple of evening class courses, one in brickying, and the other in plastering. And, because I actually like learning I did the sparkys course over here in the US where I live now, and at the moment I'm doing an undergraduate construction management course by distance learning.
Then there is my Mrs; she was in mid level admin jobs and would have stayed stuck there without a degree. So she sat down and mapped out a pathway to climb the greasy corporate ladder to the top of her profession in HR. She got her degree at 32 (full time), quickly followed by an MBA (part time), she already had her professional qualification as a member of the institute of personnel and development (MIPD), her MBA bumped that up to Fellowship. She also did some work sponsored courses in psychological testing, behavioural interviewing, employment law. At the same time she was getting more qualifications she would look for the next job up the ladder every two to three years, eventually she was well known enough so that headhunters called her. She likes admin, go figure.
My point being; I jumped in thinking, "yeah I can do that". But, I hated it when it came down to it. I should have really sat back and thought for a while and if I had followed my interests I would have either become a Porsche mechanic, or studied construction at uni. Whereas my Mrs excels at admin, people management, and corporate politics.........FFS I can't even balance the chequebook.
So have a serious think - have a goal - make a plan.
