It does not matter how much talent one possess in matters of luck.

In order for the light to illuminate the darkness must first be there.Same way how success needs failure and happiness needs sorrow.

When one feels like giving up when you must continue and do is a lot different from when you must yet can't. Don't lose hope if you know you are going to get 6 hours of sleep and still be tired rather get 3-4 finish your job and take a nap when possible. Use an energy supplement until then.Sure it might take a lot more out of you but you will get a lot more back.

If you are truly an interesting person you never feel lonely even if you are.
