Venting every feeling isn't mature. Learning to deal with uncomfortable and unpleasant feelings is an important aspect of maturity.

Make decisions from the strong part of you, not the weak.

That which is horrifying to you don't do to anybody else.

Remember that feelings or emotions emanate from the more ancient, less evolved, lower part of the human brain, while thoughts are a product of our highly evolved, uniquely human, outer part of the brain.

Because it's possible to do, and you have the right to do it, doesn't mean it's the right thing to do.

Go do the right thing.

Depth has one address: fidelity in love.
