When you are lonely for a while don't get restless, if you had born alone, you are going to die alone then for sometime you can certainly live alone.
When you are angry try your best to go to sleep, it keeps you away from speaking, writing and thinking while you are angry.
Ability, experience and books have solution for all the problems.
All my problems bow before my stubbornness.
Education makes your maths better, not necessarily your manners.
