With most spiritual matters, different things might work best for different people, but I have no reservations saying everyone should meditate.
Regular meditation is invaluable in aligning with God’s Will, with the way things are — however you want to say it — and by so doing, in reducing anxiety and self-driven suffering. It changes you.
The promise of a devoted spiritual life, of which meditation is an invaluable part, is serenity — not that nothing bad will ever happen, but that you will be able to walk through setbacks, disappointments, and even outright tragedies carried by a trust that things will be OK; that in everyday life you will not be anxious, restless or irritable; and that in good times you will be fully alive to enjoy them.
(From Meditations by Rev Philip Rose)
