Successful Evangelism? See the book of Acts.
41 Those who accepted his message were baptized, and about three thousand were added to their number that day.

That's halfway through the book of Acts. I do see mention of numbers of people coming to the Lord. I don't see much mention of "I'm just planting seeds and hope something happens down the road." I don't see much mention of preaching open air. I don't see much about passing out tracts.
