"True happiness is enjoying the present without anxiously depending on the future."
Seneca
Another of Seneca's strategies, and one of the easiest to carry out - and yet surprising and fun - is to learn to temporarily give up something even if you don't need to. For what? For two things: on the one hand, to verify the truth of what the Stoics tell us: we don't need as many things as we think! And on the other, to fight against the habituation process of the human brain: we get used to things, especially pleasant ones, and in the end we stop enjoying them as at the beginning.
Do you want to take the test like Seneca?
Think of something you enjoy daily, but take for granted, such as a cup of coffee in the morning. For a week, stop drinking coffee! The Stoics took him even further: they occasionally put on old clothes, slept on the street, ate the worst they could find. But it is enough to leave the coffee, or whatever you enjoy, for a few days, to resume it a little later with more desire, with a greater feeling of gratitude and a more intense capacity for enjoyment.
