Nothing we learn in this world is ever wasted and I have come to the conclusion that practically nothing we do ever stands by itself. If it is good, it will serve some good purpose in the futue. If it is evil, it may haunt us and handicap our efforts in unimagined ways.

Nothing goes really to waste if you're determined to learn.

It is here, I think, that the most important phase of education appears, in the capacity to learn from each thing you see, from each fact you acquire, from each experience you have, from each person you meet. And nothing you learn, however wide of the mark it may appear at the time, however trivial, is ever wasted. In all my life, nothing I have ever learned has failed to be useful to me at some time or other, often in the most unexpected way and in some quite unforeseen context.

The only things worth learning are the things you learn after you know it all.

Nothing is a waste of time if you use the experience wisely.

No education is ever wasted and everything you learn is helpful in acting.

Learning without doing is wasted. If I don’t use what I learn, then it was pointless! How horrible to waste those hundreds of hours I spent learning, and not turn it into action.

Nothing was worthless. Not if you knew who needed it. Not if you knew how to salvage it.

You never know how useful even seemingly insignificant knowledge can be.

How to successfully learn nothing:

• Ignore the fundamentals.
• Study the latest tips and tricks.
• Don't waste your time reading.
• Build shallow, broad knowledge.
• Listen to all the newest books that come out.
• Become a master of planning but skip execution.

Remember that no piece of honestly conducted research is ever wasted, even if it seems so at the time. Put it away in a drawer, and ten, twenty or thirty years down the road, it will come back and help you in ways you never anticipated.

What is the sense of knowing things that are useless?

Knowledge has no value except that which can be gained from its application towards some worthy end.
