Enter the streets that you have never been to for the sake of the concealed beauties and the hidden truths!

If you don't sow your field what harvest other than thorns and weeds can you anticipate?

If you have good friends, don't look for treasure because you are already rich; if you have just treasure, look for good friends, because you are still poor!

A great idea can change the world; but to change the universe, men need even much greater ideas!

Do not hold an idea tightly! There is always a possibility that what you believe might be wrong! Hold your ideas loosely so that you can easily get rid of them once you have realised that they are wrong!

Window washers increase the vision in the windows of the buildings; wisdom quotes do the same thing in the eyes of the people!
