Courage isn’t having the strength to go on — it is going on when you don’t have strength. – Napoleon Bonaparte
Having the strength to go on is capacity. You either have it at any given moment, or you don’t.
Want more capacity?
Whatever you’ll need when things get tough, develop greater amounts of that.
Then you’ll have something you can use when you need it.
But what if you don’t think you have the strength to go on?
Then you need a different thought.
And when you think differently, you’ll feel and act differently.
Think courageously and you’ll be able to go on.
Again, it all comes down to thought.
