"Achieving our evolutionary imperatives brings us positive emotions that range from contentment to great joy.

We just need to be prepared for the fact that these feelings won’t last.

Guard your happiness to stay healthy. Happiness is critical for physical health.

If you are sacrificing your happiness for something that isn’t incredibly important, you should ask yourself:

"How long has this situation lasted and how long is it likely to last in the future?"

Short-term sacrifices can be sensible, but long-term sacrifices should be avoided if at all possible.

If you must sacrifice your happiness to achieve other goals, try to prepare a time line and stick to it.

Otherwise, you might wake up one day to find your short-term sacrifice has been going on for years, and your happiness and health are a thing of the past.”
