I'm a grumpy scrooge, actually.
Some people advocate for drugs as a tool for interior change, but I've no experience with them. I think they can easily become a cheap escape.
I've been reading up some stoicism and Buddhism, I think there's a lot of truth there. Abandon every attachment, everything is transitory, seize the day. It's liberating to get rid of things you don't need, but when you get to the big, real "burdens"... it's not that easy.
In a sense, it's interesting that you have all the equipment you need to fix this thinking problem, all in your brain.
We live in more comfortable times than the past. So much pain can be treated now, although more pain is created as a result.
I have so much time left when I see things in this perspective. Isn't it strange that I'd rather think that I will never reach goals I don't believe in anymore, than that I have no goals to reach and I can do whatever, something else, or nothing just the same?
