Live when you have it.
Live every moment of your life.
Life is pretty strange, the time you are living right now no matter how, in future won't last and you miss this exact moment again, wanted to live every second of that memory again and correcting the mistakes you have made, you will be able to feel that moment again but you won't be able to correct it because you will be the only one feeling that moment alone. Alone in your own mind. You won't be able to correct it because its gonna be to late. So, it is better to live it now, when you have it.
