Get around what exactly? I don't think he is saying he got around anything - just that he dropped things he didn't like.
If I know that then I certainly wouldn't be this depressed
It probably doesn't sound useful, but there probably isn't a single simple answer to how. BUT - more usefully, there are simple answers to when. Things will get awesome in somewhere between 1 and 3 years - as soon as you find fulfilling things to do, with people who get you. This will happen. It will take longer than you would like, or seems reasonable, or be easy, but it is achievable.
Eventually, I got to the point where I could afford to travel a bit. And here's where the awesome part comes in. When I went to Athens, I could visualize Hadrian walking through his arch down to the temple of Zeus. Or in Florence, walk the exact same streets as Michelangelo and see exactly where Savonarola was burned to death.
In Rhodes I could see the approach the armies of Salah ah-Din had to make to assault the fortress of the Knights of St. John. It wasn't just a wall, or a bunch of bricks, it was a living, breathing piece of history. And knowing the history of it, I felt connected to it.
And now that I know that history can be so enlightening, I seek it out where I don't know it. In Korea I learned about King Sejong the Great and why he's great, and suddenly I find I'm interested in linguistics and invented writing systems (great site btw http://www.omniglot.com/). And I find connections between things everywhere!
It's just history, but other things in life suddenly have a vibrancy and flavor I never saw, because I never knew how to see.
Well I dropped boring things, and things turned out alright. Just make sure you aren't using that as an excuse for avoiding things that aren't as easy. I never found Math as easy as I'm sure some of the Math genius on HN find it, but I didn't drop it either, for example.
I do agree that developing a good work ethic is important.
