With the new day comes new strength and new thoughts. - Eleanor Roosevelt

Do the things that interest you and do them with all your heart. Don't be concerned about whether people are watching you or criticizing you. The chances are that they aren't paying any attention to you.

...no matter how avid they themselves may be for praise and appreciation, people are often niggardly in giving it to others, however merited it is.

I think everyone, at some time in his life, has this happen to him, comes face to face with the bitter realization that he has failed in something that means a tremendous amount and probably in a relation that is close to him. Life teaches you that you cannot attain real maturity until you are ready to accept this harsh knowledge, this limitation in yourself, and make the difficult adjustment. Either you must learn to allow someone else to meet the need, without bitterness or envy, and accept it; or somehow you must make yourself learn to meet it. If you refuse to accept the limitation in yourself, you will be unable to grow beyond this point.
