"The reason why we delay practicing is because we always think that we have more time.

When you wake up in the morning, you should always say to yourself, “I am still alive – I did not die. I should finish this great work. There is no tomorrow.” At night when you lie down to sleep, think about how much you practiced that day. If you spent more time thinking and sleeping than practice, then you should strongly urge yourself to practice more every day and do it!" - Zen Master Man Gong
