I would like to tell you how you turn the bad into good. How to change the point of the view. But there is no universal rule.
You can read tons of tutorials on how to turn things around. And it’s great to know them. Yet there is only one rule when it comes to you and it’s a thing you learn by trial and error. You have to find what works best for you. Nobody can’t figure anything out instead of you. They can only show you the possible ways that worked for others.
Sometimes I manage to see, sometimes I don’t. The worst thing for me is to give up to these kinds of moments.
If I only see the bad side, I’d go for a walk. Or a hike. Clearing myself from as many distractions as possible and let myself just be. This usually clears my point of view. If it doesn’t work, I’ll do the same thing for as many times as necessary. Consistency is what works for me. But it’s not always easy to be consistent though.
