You want to write the perfect application; so you don’t apply.
You want to produce the perfect article; so you don’t write.
You want to make the perfect pitch; so you don’t take up the opportunity to present.
What’s the difference between striving for perfection and striving for good quality? The former lowers your productivity and increases mental stress and strain; the latter increases the probability that things get done.
Who says it has to be perfect anyway? You do. And then who misses out? Well, you do.
For goodness sake, give yourself a fighting chance. If you want to win the lottery, you’ve got to buy a ticket.
Opting for ‘good’ over ‘perfect’ doesn’t mean you’re a loser. Let good enough be good enough; especially if the alternative is to do nothing and give up altogether.
