Either it’s a project you focus on, or a project you don’t focus on.
And projects you don’t focus on aren’t projects, they are distraction.
Side hustles do exist, although they are a project subject to serious chance of being a distraction.
Too much focus projects cause health problems. Too little cause boredom.
It’s up to us to find the right amount of projects that matter enough to deserve our available focus and eliminate the rest.
