Volunteering to help others is the right thing to do, and it also boosts personal happiness

Focus not on doing less or doing more but on doing what you value.

If you're a night person you can barely get out of bed in time to get to work or get your kids off to school. You're at your most productive and creative much later in the day, and for you, something like getting up early to go for a run is not going to set you up for success because you're not a morning person.

Sometimes, counter-intuitively, it's easier to make a major change than a minor change. When a habit is changing very gradually, we may lose interest, give way under stress, or dismiss the change as insignificant. There's an excitement and an energy that comes from a big transformation, and that helps to create a habit.

There's also something about your bed; it's sort of a symbol of yourself and of your marriage, if you're married. Making your bed doesn't seem to be an important thing in a happy life, and yet it can be that tiny foothold into a more orderly life that sometimes people need.

I spend a lot of time saying to myself, "Well, is that really what I like to do? Is that really something that makes me happy?" and letting go of the things that don't make me happy.

Act the way that you want to feel.
