Nature is impersonal, awe-inspiring, elegant, eternal. It's geometrically perfect. It's tiny and gigantic. You can travel far to be in a beautiful natural setting, or you can observe it in your backyard - or, in my case, in the trees lining New York City sidewalks, or in the clouds above skyscrapers.

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.

Get enough exercise and sleep: Sounds trivial, but it's not. You may have the urge to work 24/7, to skip the gym and to stay up late to get a few more things done. That's short-sighted. Exercise and sleep are critical to having the physical and mental energy necessary to meet a challenge.

A blog is something that, everyday there's a new thing and that's part of the fun of it, you're just constantly moving forward. A book really gives you more time to reflect and think hard on things very, very deep.

Some kind of clutter is difficult - letting go of things with sentimental value, sifting through papers - but some clutter I find very refreshing to clear. I drive my daughters nuts because I'm always wandering into their rooms to clear clutter.

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.

What's fun for other people may not be fun for you- and vice versa.
