In Buddhist practice, there are four thoughts that remind us of:
(1) the preciousness of this human life;
(2) that we are going to die;
(3) that karma follows us everywhere; and
(4) that samsara is a waste of time that only supplies suffering.
Memorize them. They will reframe your life, focus your mind, and advise you in everything you do.
As Samuel Johnson, the author of the first English dictionary, said, “When a man knows he is to be hanged in a fortnight, it concentrates his mind wonderfully.” What would you do if you had six months to live? What would you cut out of your life? What would you do if you had one month, one week, one day?
The Indian master Atisha said, “If you do not contemplate death in the morning, the morning is wasted. If you do not contemplate death in the afternoon, the afternoon is wasted. If you do not contemplate death in the evening, the evening is wasted.” The four reminders remove the waste.

Recently, I created another website that covers The Four Thoughts in more detail. The website can be found at http://the-four-thoughts.org/
