Take any path you like; follow any prophet you like; but have only that method which suits your own nature, so that you will be sure to progress.

True progress is slow but sure.

Unless we progress, we regress.

Discontent is the first necessity of progress.

There is a subtle danger in a man thinking that he is "fixed" for life. It indicates that the next jolt of the wheel of progress is going to fling him off.

Do not look back upon what has been done. Go Ahead.
