Learn from yesterday live for today hope tomorrow. The important thing is not to stop questioning.Life like riding a bicycle. To keep your balance you must moving.We cannot solve our problems with the same thinking we used when created them.If can't explain it simply don't understand well enough.A person who never made mistake tried anything new.Look deep into nature and then will everything better.Strive be success but rather of value.I have no special talent. I am only passionately curious.
