You said it all bro but I want to chip in some things, not all positive thinking are healthy thinking I will give you an example or illustration, for a business man who probably has failed for a particular days activity let's assume yesterday's activity and has been thinking about a particular way to solve the problem of course you know it's a positive thinking to find a solution to his problem but it might not be a healthy one because it involves stress it involves also taking much of his time in order to find a solution to a particular problem, when someone thinks healthy then it means the person is firstly happy and also has a rest of mind that's when the thinking can be a healthy one but when someone has a problem and on the course to find a problem solution he or she might be in a deep thought or how to solve it I think that type of thinking might not be a healthy one, so I think whatever we do we should be happy first and have rest of mind in order to get our desired positive thinking.
