How does one develop faith and trust for the future?

I’m a kind of guy who won’t step foot from A to B unless I’m certain that B leads to Z… I used to take leaps of faith in grade school when I knew someone would catch me if I fell… but that’s gone now… and I can’t seem to go to the next level…(like picking my future job or religion or major ect…) I just hide at my parents basement and sleep as comfortably and as long as possible…
How do I get the inner strength to move on? Or have I peaked in life and should stay where I am for now?
