The past no longer exists; the future has not yet come; there is only the present. And only in the present can the divine nature of the free human soul be manifested.

Then Jesus said unto them, Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth.

— John 12:35

Everyone knows that our habits are improved and strengthened through their exercise. In order to be a good walker, you need to walk a lot; in order to be a strong runner, you need to run frequently; in order to be a perceptive reader, you ought to read as much as you can. The same is true of your soul: if you become angry, you must know that you not only perform evil, but you also create an evil habit, and you increase your potential for further evil.

— Epictetus

If you want to do a good deed, do it now. The time will pass, and you will not have the chance again.
