The only time people attempt to choose a side in the quality vs quantity debate is when they either

A. Lack the skill level to produce quality results
B. Lack the willingness to produce in large amounts.

Anyone who has both A and B has no problem doing both. At the same damn time.
If you're good at something, do it as much as you possibly can. Either/Or is for poeple who think in terms of scarcity and limits. That's not you. We think in terms of all of it.
