The key to life is accepting challenges. Once someone stops doing this, he’s dead.

I have learned that success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome while trying to succeed.

To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.

I find the great thing in this world is not so much where we stand, as in what direction we are moving: To reach the port of heaven, we must sail sometimes with the wind and sometimes against it—but we must sail, and not drift, nor lie at anchor.

Stand up to your obstacles and do something about them. You will find that they haven't half the strength you think they have.

Success is determined not by whether or not you face obstacles, but by your reaction to them. And if you look at these obstacles as a containing fence, they become your excuse for failure. If you look at them as a hurdle, each one strengthens you for the next.

By prevailing over all obstacles and distractions, one may unfailingly arrive at his chosen goal or destination.

Plant seeds of expectation in your mind; cultivate thoughts that anticipate achievement. Believe in yourself as being capable of overcoming all obstacles and weaknesses.

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits.

One would think it would be most unwise in a man to be afraid of a skeleton, since Nature has set curious and quite insuperable obstacles to his running away from it.

Against all odds and despite all the obstacles, we are going to make it.

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.

There is a force that somehow pushes us to choose the more difficult path whereby we can transcend the mire and muck into which we are so often born. Despite all that resists the process, we do become better human beings.

Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion.

If we all can persevere, if we can in every land and office look beyond our own shores and ambitions, then surely the age will dawn in which the strong are just and the weak secure and the peace preserved.

The necessity of the times, more than ever, calls for our utmost circumspection, deliberation, fortitude and perseverance.

Continuous effort — not strength or intelligence — is the key to unlocking our potential.

Through perseverance many people win success out of what seemed destined to be certain failure.

Faced with a mountain, I will not quit. I will keep on striving until I climb over it, find a path through it, tunnel under it, or simply stay and turn it into a gold mine.
