Finish what you start without being a perfectionist

Instructions

Do the hard things first.
Prioritize doing the tough aspects of your work first. This way, you’d be encouraged to finish up as your tasks get easier down the road.
Know when to stop.
Of course, you’ll want to keep tinkering, tweaking, and running the problems over in your mind. But you need to be able to stop yourself and say that this is “finally done.”
Get help.
If you can’t stop yourself on your own, have trouble with the last mile on your projects, or know you can fall prey to perfectionism, then find partners who can cut you off and balance you out.
Always get back up.
Keep in mind that it’s never going to be all good. You’re going to mess up sometimes. You’ll make mistakes and miss the mark. At these times, you must have the discipline to get back up and try again.
