Sometimes I feel a lot of things but I keep it in. I'm sure we all have this built-in radar of what we predict and when it happens, we feel 'I knew it'.
When someone gets a success, and we, too, have done good work and sometimes even better work than the person who has just triumphed, we wonder: Why did success pass me by?
Try to do unto others as you would have them do to you, and do not be discouraged if they fail sometimes. It is much better that they should fail than you should.
