[ Quality in quantity ]

Doing something well, once, might be considered beginner’s luck. For example, running your first 10km in under 45minutes, or having your first book proposal accepted: these are amazing accomplishments. Doing an impressive thing once is good for the ego, and yes the bragging rights are worth it. No problem with that.

Doing things well over and over again is probably more satisfying. In the work world, there are many tasks that need doing many times. For example, writing reports, sorting through data, solving complex design problems.  The best way to improve is to do them many times. Quantity builds quality.
