Careful with time. You only get 24 hours in a day.
Careful with words. You only speak a few thousand per day.
Careful with money. Even if you're wealthy, there's just a finite amount in the bank.
Even if they do not practice what they understand to be the best, there seems to be no misunderstanding about the need to be careful with how these limited resources are used so that the most creative and useful results manifest.
However, with sex, there continues to be many people who will argue that sexual energy can be freely given to whomever whenever without detrimental results.
The healthiest of mind and body seem to be as careful with when, where, and to whom sexual energy is released as they are with where they spend money, what words they speak, or how they spend time.
You can be wealthy without being cheap.
You can manage time well and have more time for what's important.
You can guard words and say more.
You can be careful with sexual energy and have more and better sex.
