For a 26 year old my advice would be pick something.
I know its hard to see from where you are, but at 26 you still have the starters gun ringing in your ears. You've barely started.
If you don't know what you want to do, just pick something that seems vaguely appealing or worthwhile and throw everything you've got at doing that. Try not to get distracted from it until you've achieved something in that area.
It might not be what you end up doing for the rest of your life. But even if you spend 10 years doing it, you'll have achieved something in a specific area, hopefully earned some money, had a few life experiences and you may even know what you really want to be doing.
A worse thing is to realise later that you've wasted those years casting around for something, you've got weighed down by the trappings of life (financial commitments, relationship commitments, property commitments) and you've suddenly realised what you want to do and... you can't.
Any progress you make in anything will put you in a better position when you figure out what it is you're meant to be doing.
