Sometimes the best gain is to lose.

As to pay, Sir, I beg leave to assure the Congress that as no pecuniary consideration could have tempted me to accept this arduous employment at the expense of my domestic ease and happiness, I do not wish to make any profit from it. - George Washington,

Our farmers round, well pleased with constant gain, Like other farmers, flourish and complain

And if you mean to profit, learn to please.

Gain cannot be made without some other person's loss.

For everything you have missed you have gained something.
