You may carry the message. If he's fortunate, he'll do it. Even he does not do it, you are carrying the message, you become recognized by Kṛṣṇa. Na ca tasmān manuṣyeṣu kaścin me priya-kṛttamaḥ (BG 18.69). You are doing sincerely, then you are recognized by Kṛṣṇa.
Just like a canvasser, salesman, goes to the market, tries his best to secure some business. The master sees the report how he has worked. Even though he has not secured a single paisa business, but he has tried to introduce the goods, then he's bona fide. He's bona fide. Similarly, we have to simply carry the message of Kṛṣṇa and try to convince people. If one is convinced, it is good; if not, doesn't matter, I am not . . . going . . . then you are recognized by Kṛṣṇa. Recognition means you become the dearest servant of Kṛṣṇa. Then what do you want more? If Kṛṣṇa recognizes that, "You are My most dear servant," then what do you want more?
