I did an interview with a guy named Marcus Anderson some years back and he said something that stuck with me:

"There's only one level of commitment. Total."

That's a pretty powerful way of looking at things. We can only commit to so many things. It's easy to catch myself wanting to be an expert in a lot of areas, but it isn't possible to fully commit to everything. Some people spend their whole lives being a musician, an artist, an entrepreneur. You can get pretty good at a lot of things, but most likely not world-class at all of them.

If you want to be world-class at something, it probably takes a level of commitment that's far greater than we think.

It's worth asking: what's the one thing you're willing to go total on?
