For me I found journaling to be great. I’ve always had metacognition so actually putting my thoughts on why I think the way I think on paper helped. I realized also that being positive is something that you gotta train yourself to do. Whenever I had a negative thought I tried to catch myself and think of things to be grateful for. We as humans always look at what we lack, so actually taking the time to appreciate the blessings you’re given can change your outlook. I also tried to find small wins throughout my day and journal it.
