Anyone can theoretically sit down and study for the equivalent of a university degree. Most people don’t have the motivation or discipline for that.
Half the point of the degree is that it pushes you to get it done. (The other half is verification that you did it.)
If you still can’t do it, then it isn’t so easy after all, is it? The main challenge isn’t how big your brain is. It’s actually putting in the work.
If you can’t find enough self-discipline to get through it, you’re going to regret it later.
It’s important that he disabuses himself of the notion that he’s really good at this if he tried. The trying is the part that’s the challenge. They make the ability to understand part relatively easy. That’s the whole point of college.
The tip is to change his perspective and stop thinking that he’s above it. It may not be the only tip, but it’s a big one.
The world is filled with people who used to be brilliant slackers when they were young who did nothing with it.
