My question to you, with respect, is this: why not just reduce the amount of hours per day you spend on serious, solitary intellectual work and fill the balance with externally oriented, social activities till you find a maintainable balance of sociability vs. studying?

It's not like I have some slider on my desktop, with "sit in a box, autistically rocking back and forth, counting numbers" at one end, and "rakishly sample the epicurean delights of the world" at the other. I have time and work and study commitments. I have externally-imposed scheduling. I have inscrutable internal motivation levels that need to be contended with.

It's a case of resource management, and occasionally when managing those resources I'll have to focus on one area to the exclusion of another. That's fine. It's not something there's a "solution" to. It's a condition all moderately busy people have to operate under.
