“You mention you like to speak now very often, but the first business should be to preach to the devotees. It is better to maintain a devotee than to try to convince others to become devotees. Don’t be too much concerned for the time being with non-devotees, now we must fix up what devotees we have got in the knowledge of Krsna consciousness, then we will succeed. What good are many, many devotees if none of them are knowledgeable?”

(Srila Prabhupada to Satsvarupa, 6/16/72)
