None of us is as smart as all of us.
Nothing can add more power to your life than concentrating all your energies on a limited set of targets.
Nothing endures but change.
Nothing focuses the mind better than the constant sight of a competitor who wants to wipe you off the map.
Nothing gives a person so much advantage over another as to remain always cool and unruffled under all circumstances.
Nothing is more harmful to the service, than the neglect of discipline; for that discipline, more than numbers, gives one army superiority over another.
Sir James Barrie
Nothing is really work unless you would rather be doing something else.
Often he who does too much does too little.
On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.
One chance is all you need.
