The less you complex about things that doesn't affect you, the more happy you life.

@Alex Boke Among all of them, the ones that work best for me are: 1. Design an ambient that helps you doing and remembering your habits. 2. Follow and be with people who are also trying to reach the same goals as you do. 3. Say all aloud all the benefits or disadvantages of the thing you're going or you need to do (you can even exaggerate them). 4. Design a version of your habit that takes of 2 or less minutes to perform, be conscious that the only thing that matters is to never miss a repetition of your habit, it doesn't matter how much you do on a repetition. 5. Restrict yourself to do something you like until you finish the thing you need to do. Or just restrict a thing you most not do (ex: bricking your phone). Make your bad habits very hard to do and your good ones very easy. 6. Make a habit tracker: make an X mark on a calendar every time you finish to do a repetition of your habit. Those are the best tricks of the book in my opinion. I recommend reading the book because it show way more tricks to help improving your life.
