To improve is to change to be perfect is to change often.

If you change the way you look at things, the things you look at change.

If there is no struggle, there is no progress.

Action and reaction, ebb and flow, trial and error, change - this is the rhythm of living. Out of our over-confidence, fear out of our fear, clearer vision, fresh hope. And out of hope, progress.

Any change, even a change for the better, is always accompanied by drawbacks and discomforts.
