Not everyone is going to be good at everything, therefore it is perfectly okay to feel as though something is impossible. The problem lies where someone gets in the way of someone doing the exact thing you thought could not be done.

When you deem that you cannot achieve something that does not give you the right to tell someone else that they cannot do it. And when they do achieve their goal, you should be happy for them and that they could do what you had once thought couldn’t be done.
