Obstacles are to Challenge You, Not Stop You

 

One who gains strength by overcoming obstacles
possesses the only strength which can overcome adversity.

- Albert Schweitzer

Real obstacles don't take you in circles.

They can be overcome.
Invented ones are like a maze.
- Barbara Sher

Obstacles are like wild animals.
They are cowards but they will bluff you if they can.
If they see you are afraid of them...
they are liable to spring upon you;
but if you look them squarely in the eye,
they will slink out of sight.
- Orison Swett Marden

Press on.
Obstacles are seldom the same size tomorrow as they are today.
- Robert H. Schuller
