What diploma or certificate courses are available for late in life students

Im 37 and by indian standards decrepit and on my death bed (laugh out loud. Apparently the abbreviation isn't allowed on this sub)

my qualifications are are 12th PCB 95%.

Life happened and I had to drop out of college. Then some more life happened and I couldn't go back. Now im restarting. I plan on getting an online degree in the future.

In the meantime are there any diplomas or certificate courses or anything else I can pursue?? Like anything at all?? I want to compile all of the avenues available for people like me irrespective of field to try my hand at everything. Can I get multiple diplomas and such??? I have no idea where to start or where to look. I feel like i was in a come from ages 19 to 36 and im finally waking up. I have to believe I can do something because if not I might as well quit life now.

Please any help or guidance on where to research or look for diplomas or certificates etc would be greatly appreciated.
