Is this true for you? I find it’s pretty easy to slip into a dissatisfied state of mind.
Not being satisfied that your current life is "as good as it gets," you want to continually evolve and grow and get more and more in the flow of work you are meant to do. This is different than being perpetually dissatisfied … it is more a continued commitment to stay engaged and happy with what you are doing.

An interesting counter thought: Are entrepreneurs and innovators more prone to being continually dissatisfied? Is that the impetus that drives them to try new things?
(FYI: Though it sometimes feels a bit too much like a self-help book, I do enjoy reading Pamela Slim’s blog. Check it out if you’re not already reading it.)
