Proverbs make the essence of human behaviour bearable.
On the contrary - human behaviour doesn't have such a tremendous impact on our thoughts. When you behave, you don't think much. You just do it! And if your habits are healthy, then you're a lucky one. Or a wise one. Discipline is in structuring your will. Strong will and work builds character. They say your character is your destiny.
Practice !!
And never forget: wether you're doing or non-doing
( wise or unwise for the observer  ) ~ always listen to your heart.
The heart has 5000 times stronger electro magnetic energy than our mind. Don't exhaust yourself overthinking or overworking.
Discipline doesn't suffice for moments in which we have to make a decision. Some decisions are important. Don't ***** your life!
Don't think too much!
