Feeling rejected or even humiliated once in a while is actually very heavy in the long run.

The solution is to not avoid all relationships and isolate yourself altogether. The solution is to hang out with smarter and wiser people who actually care about finding a long-term, sustainable solution.
They don't get emotionally reactive and dramatic. They don't get offended about being proved wrong. And it feels effortless and actually revitalizing to be around them.
