Perseverance is about as important to achievement as gasoline is to driving a car. Sure, there will be times when you feel like you're spinning your wheels, but you'll always get out of the rut with genuine perseverance. Without it, you won't even be able to start your engine.
The opposite of perseverance is procrastination. Perseverance means you never quit. Procrastination usually means you never get started, although the inability to finish something is also a form of procrastination.

This fault-into-virtue syndrome is a common defense when people are called upon to discuss their weaknesses, but in the end it's just a very pious kind of excuse making. It certainly doesn't have anything to do with what's really behind procrastination.

You're still stuck. You're still going nowhere. You're still overwhelmed by whatever task is before you. You
