Hi petitvoyager,
It sure is easier to be seeing someone who has a sense of purpose! Some people, though, are just “there”. There’s nothing wrong with being just “there”, but I can see how it must be maddening to you!
Can you take him along on your adventures? Play games like (don’t remember the exact name) “What Would You Do”? Ask for his advice and have his input be the deciding vote?
It’s not that you want to fundamentally change him (you can’t), but maybe slowly and gently tease out strands of passion, curiosity and interest.
Good Luck!
Inky
