There are definitely times when it's fully appropriate to raise your arms in victory. Usually, it involves years and years of practice and finally breaking through to achieve a long-desired goal. Accomplishment takes time!
But it's important to remember that perfection is an ideal that you chase, not something you can expect to reach all the time. It's an aspiration, not an expectation. But hey, when you do achieve it, by all means celebrate. We're celebrating right alongside all these folks who have something worthy of a high five.
