Please don't believe that purpose crap.
We are not God's children. We weren't born to serve a purpose. We came into existence bcoz our parents had sex. Period!
Now that we have established it, understand that since there's nothing defined for you, it's a Privilege. You get to decide what you wanna do!
You can literally do anything! If you have tried enough and didn't enjoy something, move on to the next thing you want to try!
It's okay to not know what your future holds for you. It's okay to experiment to figure out what makes you happy. This is true for everything that you do - friends, food, career, hobbies etc.
It's only fair to take time find out what you like by experimenting!
I understand the psychological need to go back to the past, but it only is gonna ruin your fun in the present. There's nothing wrong to reminisce the past as long as you can snap back to reality
TLDR - there's no right path, there's nothing defined for you. It's entirely you who crafts your own path. Your decisions are based on what you want in your life and what you are willing to sacrifice for it!
If you take a path and screw up, it's fine, from that point make a decision to either continue the path or switch.
Don't be so hell bent on not failing!
