Thomas A. Edison
Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.
The three great essentials to achieve anything worth while are: Hard work, Stick-to-itiveness, and Common sense.
Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.
Thomas A. Edison — quotes and aphorisms
Opportunity is missed by most people because it is dressed in overalls and looks like work.
Just because something doesn't do what you planned it to do doesn't mean it's useless.
Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
