Anger will not solve the issue

after a long journey of not being satisfied about my life , I start to search in how to cure the issue from its root, not only solving one issue but also I discovered that the way I'm thinking about everything around me is not correct. so basically instead of being angry on someone or something just ease this thing and let it go. This universe is here to serve us and instead of one way to solve any matter ,there are many many ways , only people with narrow vision ,will block their minds on finding the easy way to handle anything in this universe
