Optimism to some extent too.

But first: What is dopamine, exactly?

(More on those in a minute.)

One of Courtin-Clarins’s easiest recommendations for cultivating that optimism?

Being optimistic is something you have to work at every day, he says.

And to do that, give yourself something good three times a day.

This brightens your thoughts and encourages you to see the glass as half full.

It changes the way you see things from day to day and stimulates the secretion of feel-good molecules.

Easy, but something you must consistently work at.

All studies agree that between 30% and 50% of personality traits are biologically determined, says Testa.

The latter is responsible for feelings of motivation and reward.

It promotes a feeling of pleasure, Courtin-Clarins explains.

And yes, it is possible to generate them on our own.

It’s been proved that both natural and voluntary laughter generates dopamine.

When we smile, there is an increase in endorphins, neuropeptides, dopamine, and serotonin.
