You may use the term "good enough" for a reason but it may not be the same as others do. Indeed it's a relative concept comparing two items and putting an end to never finishing work.
|There'll always be someone better than you, but what matters most is how good you are in the category you're fighting in|
However be aware that your "good enough" may not be the same as the "good enough" of others. Don't hesitate to challenge the criteria used, the need to stop now, and how hard it'll be to resume work on it later compared to now.
And don't forget to check the relative aspect of it: if someone else's better than you, then you're not good enough anymore!
