As someone in the midst of trying this I can tell you personally it’s not all it’s cracked up to be. I think I’m starting to realize that this person is beyond my capability to help and all the time I’ve wasted helping them could have been spent improving my own situation
> this person is beyond my capability to help
I think there's something to be said about the difference between "solving other people's problems" and "solving someone's problems". If the whole idea is to not be so invested into one life and get perspective, volunteering somewhere ought to be on a different league then trying to sort one specific person's life.
From my personal environment: there are many people that are beyond my capability to help.
It sucks, but libertarians were right. ;p
That said, depression, fear, and lack of confidence are multi-faceted things with many different mitigating and exacerbating causes. Even diet and digestive ability can play a role! I find light exercise to mitigate the effects, too. But a sense of warm-heartedness toward yourself and others will be helpful no matter what.
