Procrastination is meaning to do something and somehow not getting around to it. Explicitly deciding "I'm not going to work on it until X (or never)" is not procrastination, it's making a decision. It may look the same on the outside - the job does not get done - but it's different emotionally, as in the latter case you get to stop thinking about it.

No, you do what you can now. If you start to hesitate because of perfectionism, tell yourself that you can fix it later.

Not if you get motivated and do the stuff that needs to be done, by telling yourself to ignore all the bells and whistles and "postpone" them.
