Get a job, get married, have children. In that order. It is a progressive program, proven time and time again in real-world trials. If you stall at any of the lower steps, do not progress further until you achieve proficiency. If you aren't ready for a job yet because people are asses, try some tolerance building exercises like staying in one lane when driving, no matter how slowly the person ahead of you is driving.
The way to get stronger is to lift heavy things. The way to become tolerant is to be in annoying situations.
