No sir!!!!! Don't you dare trim that beard of yours. Let it continue on to your original goal. You don't want to let yourself down. And you don't look Amish at all. My wife was from Amish country in Indiana, and they don't have a beard like yours at all. Theirs is always shaved to a chin curtain without a mustache. You have everything it takes for a really nice looking beard. It is not just respectable, but handsome on you. Your friend has a nice mane, but don't discount yours.

Keep growing, and be proud of your great beard...
