Motivation is how. If you fall asleep, say, in a sorting - then for some reason a person has a motivation to take and do dumb. And sluggish excuses are not sought for some reason, and doubts with throwing somehow do not arise, and "I can't" is not turned on. The solution exists, including the non-existent one. Even time always exists.

If it wasn’t so, it was heroic. Do not lie to yourself and others.

Human needs are divided into two large groups: natural and cultural. The first are programmed at the genetic level, and the second are formed in the process of social life. Comparing them is incorrect.
If you do not go to the toilet in time, the result is unambiguous and obvious. If, for example, being lazy to learn English, it will not lead to anything tragic.
