Do what you can, with what you have, where you are

Time stays long enough for anyone who will use it.
One realizes the full importance of time only when there is little left of it.
Many of us spend half our time wishing for things we could have if we didn't spend half our time wishing.
Time heals what reason cannot.
Nothing is a waste of time if you use the experience wisely.
Time is a great teacher, but unfortunately it kills all its pupils.
Don't say you don't have enough time. You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michaelangelo, Mother Teresa, Leonardo da Vinci, Thomas Jefferson, and Albert Einstein.
You will never find time for anything. If you want time you must make it.
It is never too late to be what you might have been.
A minute now is better than a minute later.
Today is the tomorrow we worried about yesterday.
One thing you can't recycle is wasted time.
You may delay, but time will not.
Half our life is spent trying to find something to do with the time we have rushed through life trying to save.
