Life isn't complicated at all. It's us who make it look that way. We over-analyze and overthink everything. But it all comes to set of simple decisions. You do/say something or don't. If you have some problems in your life don't look at them as such. You can't change the situation but you can change how you react to it. You can cry, be depressive etc or you can do something about it. I always try to look my life as a computer programmer. If I want to correct something I don't patch it, I debug it so I find a root cause of problem and fix that instead of trying to only fix problems on surface.
