Having a low opinion of yourself is not 'modesty.' It's self-destruction. Holding your uniqueness in high regard is not 'egotism.' It's a necessary precondition to happiness and success.

In most cases, our thoughts about experiences that have happened to us cause greater grief than the events themselves. Understanding it may be difficult and require some effort, but remind yourself as often as you need to, that past and future exist only as stories in our minds.
