Happiness seems to demand at least a little bit of many fullfilling things and many kinds of exercise in life but mostly does not bear overly much of them. So 15 minutes of something each week is often much better than nothing at all, if it is a thing that brings more happiness to just you or some incredient of the healthy natural ages old ways of living, but anything more must be decided according to what feels good for you. You have to find a way of living that is right for just you.
If you try somebody else's clothes or some opinion of theirs, it is most likely that it suits just their character but not yours. Similarly with things to do it is best to stick to your own likings and to those things that are healthy and suited to most people.
What you need varies from one day to another and from one moment to another. So do not make rigid rules of something that was once a good choise. Instead allow variation.
