It takes years to build a reputation and five minutes to ruin it. If you think about that, you’ll do things differently.

The Virtue of Temperance
Control. Discipline. Restraint. Call it what you will. But if you don’t have it, then life will be much harder. Rather than automating your life for success, your habits will be weak and detrimental. Temper your desires for excess. There is joy in moderation.
