We must exercise ourselves in the things which bring happiness, since, if that be present, we have everything, and, if that be absent, all our actions are directed toward attaining it.

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.

Happiness comes not from having more, not from having less, but from wanting what you have.
