I have a nice dose of joy and confidence each day.

*Dose* is a modest word, and the modesty is what makes it work. Not transformation. A daily amount, taken regularly, at a level a body can actually absorb.

Anyone who has been prescribed anything knows the pattern. The dose that helps is the one you keep taking, not the one taken heroically for four days and then abandoned.

So the question isn't how to feel wonderful. It's what your reliable daily portion is — the twenty minutes, the walk, the call to the one person who makes you laugh properly — and whether it survives a busy week intact.
