Do less, but better.

I've been reading Essentialism by Greg McKeown and it's been huge for the way I approach not only my startup but life in general.

So easy to get caught trying to do everything, squeeze in just one more feature, polish the marketing pitch just a little bit more etc etc. Those extra things won't make or break you. They aren't (and shouldn't be) the essence of what you are building.

Build the essence of your product/service/offering and then SHIP IT.
