Books for a guy in his mid 20s, kind of lonely, kind of stuck?

As the title says, looking for a book rec for someone in their mid 20s that’s a little stuck. The best way I can describe the kind of vibes I’m looking for is something close to Eleanor Oliphant is Completely Fine, which I loved.

I’d love something similar, from a guys perspective. Looking for purpose, looking for growth, keeping hope and whatnot.

This might not be the clearest, but thanks for the help anyways!
