Well, I tend to shrug at the "Just Starting" philosophy. In building software there may not be much cost to having a ton of half finished projects (you always learn something, even if you didn't finish it).

But for more general things in life, "Just Starting" can just add anxiety and clutter to your life.

My wife is the chronic example of this. She is a "chronic hyperactive starter", she starts multiple house chores and tasks and leaves them all half done. Over her life she has started multiple courses she didn't finish. Our house is packed with little half finished handy-craft projects tucked inside bag after bag. In the kitchen there are often half washed dishes, in the bathroom half washed clothes lying around. She is not untidy at all, she prizes cleanliness and method like a lot other people do, but she just cannot manage the anxiety of a "to-do" list.

In order to feel active she must start all that is not done yet, but somehow then abandons the task to start another.

Mainly my house work is going around the house picking up her half finished tasks and finishing them.

Just to give an alternative view... the habit of just starting is only at best 50% of getting things done, and many times it's not even the hardest part, the hardest is finishing things.
