I am dismayed to realize that much of the advice I used to parcel out to aspiring writers has passed its sell-by date.

There's a marvelous sense of mastery that comes with writing a sentence that sounds exactly as you want it to. It's like trying to write a song, making tiny tweaks, reading it out loud, shifting things to make it sound a certain way... Sometimes it feels like digging out of a hole, but sometimes it feels like flying. When it's working and the rhythm's there, it does feel like magic to me.

Like writing, running is so much about mind over matter. There are times when you have to override the discomfort and keep pushing. That capacity to endure and then prevail is just amazing.

My ace in the hole as a human being used to be my capacity for remembering birthdays. I worked at it. Whenever I made a new friend, I made a point of finding out his or her birthday early on, and I would record it in my Filofax calendar.

I wish I had coined the phrase 'tyranny of choice,' but someone beat me to it. The counterintuitive truth is that have an abundance of options does not make you feel privileged and indulged; too many options make you feel like all of them are wrong, and that you are wrong if you choose any of them.

I might have missed my calling as an editor. In the spring, the sight of my empty garden beds gives me the horticultural equivalent of writers' block: So much space! So many plants to choose among, and yet none of them seem quite right!

There will always be vain, obsessive people who want to own rare and extraordinary things whatever the cost; there will always be people for whom owning beautiful, dangerous animals brings a sense of power and magic.
