Our mind can be free if we let it. Through constraints we limit our thoughts. It's not our faults, it's how we've been conditioned over the years. It's possible to recondition ourselves but it takes effort and discipline. It's not an overnight thing that can be learnt through a book or a YouTube video. We must commit ourselves to practicing a new way of thinking that we can only truly find through self-discovery.
Cut out extraneous, mind-altering things and start practicing meditation daily.
This is the most preachy I'm going to get for now. I'm not sorry. This post is here for me later when I start to doubt the path that I've been on for years.
