Yeah, I'm really addressing the hypothetical 26-year-old me. The OP is 26 and he thinks he's at "mid-life" and is worried about not having a career. I'm nearly 40 now and am only now starting to find out what I want to be when I grow up. And I don't feel very handicapped by that! My past "careers" have all given me a lot of value and learning.
The message I'd like to convey to the OP is that he could have an adventure for 4-5 years, or even 10 years, and then worry about what career he wants to go into.
