As-salamu Alaykum wa Rahmatu Allah wa Barakatuh
Imam Ghazali (rh) says: 'It is incumbent on every person who believes in Allah and the Last Day that he should not be oblivious of auditing himself. Every breath of life is a precious jewel which can buy eternal treasures. Wasting these breaths or using them for detrimental purposes is such a great loss which no intelligent person could justify. When a person wakes up he tells himself that the only commodity he has is his life. When life perishes all his capital perishes. This is a new day that Allah has given as a further opporutnity to make amends. If He had taken his life away he would want to return for just a single day so that he could do good. So one should deem that one has died and has returned to the world for one more day. One should not waste these precious and invaluable jewels of life.
The day has twenty-four hours. One should strive today and not become lazy and lethargic lest one loses the ranks of the 'Illiyeen (the highest rank of those in Paradise) and forever live in regret.'
