“Always aim for achievement, and forget about success.”

“My mother drew a distinction between achievement and success. She said that 'achievement is the knowledge that you have studied and worked hard and done the best that is in you. Success is being praised by others, and that's nice, too, but not as important or satisfying. Always aim for achievement and forget about success.”

“Science does not aim at establishing immutable truths and eternal dogmas; its aim is to approach the truth by successive approximations, without claiming that at any stage final and complete accuracy has been achieved.”

“Success is realising the true joy and wonder of life can only be yours if you follow your own intuition, aiming to achieve your bliss.”

“People said, "Jane, forget about this nonsense with Africa. Dream about things you can achieve.”

“The only key to success in life is aiming high daily.”
