I Samuel 17:39 And David girded his sword upon his armour, and he assayed to go; for he had not proved it. And David said unto Saul, I cannot go with these; for I have not proved them. And David put them off him.
Prove your talents. Don’t make the mistake of trying to do something just because that is how others do it. Prove your own talents.
Test your calling and your weapons. Have a fervor for God but do not try to avoid getting all the necessary training to do what God has called you to do.
