Not everyone is designed to be academically bright. All of us have different skill sets. We can put lists together, for example. You might be able to play the piano, or do the floss. It's important in life to know what you're good at and focus on those skills, while avoiding the things you're less talented at wherever possible. This guy has got the right idea - he's down at a campsite, and he's already letting people know what he's useful for.
If you want someone to study the plans for a tent, or work out a route to the nearest town, he's probably not your man. If you want the tent putting together, or things loading into the car before journeying to the next town, he's the first person in line. Smart people will always need strong people, and strong people will always need smart people. It's good of him to make himself so available!
