The sower performed a simple role in the parable of the sower (Matthew 13:1-9, 18-23). He threw seed on the ground.
This is not rocket science. All it requires is time, a desire to learn a little, and a desire to spread the message to others.
After the sower in the parable sowed the seed, his work was finished. It did not matter who sowed the seed, just that someone did it. It had nothing to do with personality. It had nothing to do with the sower's clothing or attractiveness, wealth, fame, or talent. (See 1 Corinthians 3:5-9.)
That’s not to say that the sower is not important. It’s just that no one should boast. We're just seed slingers. God gets all the glory. Or at least He should.
