Like most people, I have high standards for my work and, in some things, certain ways of doing things that I consider to be the Best Way. But in a team, I must accept that other people may have ideas that are equally valid, or ideas that may be deficient in some respects but good enough. But of course, if someone is veering off course, or doing shoddy work, or could benefit from a sugestion, I'll offer my advice.
There is a balance between perfection and good enough, and between strictness and tolerance - between consistency and flexibility, dogmatism and freedom. And they are not necessarily mutually exclusive - one enhances the other, or close observance of one makes the other acceptable. Obviously if things are going too far one way or the other, one must pull back.
So it's a matter of good judgement - making the right call at the right time. I tend toward the strict side of things, and I need to be conscious of when to let up, of when it is more appropriate to be flexible.
