Pride. It’s simple, but all the same, not so simple. If you are proud of something, it’s because you created it, and you believe that it’s great.
Many parents think this way of their children, but their children gain pride in their accomplishments as well.
My parents are proud of me because they have raised me well enough that they know I can stand on my own, and that I will be able to hold my own and handle whatever comes at me.
So be proud of what you do. You never know what you can do if you just believe in yourself.
