If you are trying to achieve, there will be roadblocks. I've had them; anybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.

Michael Jordan

I can accept failure, but I can't accept not trying.

Do nots let what you cannot do interfere with what you can do.
