I can’t aim for sh*t

I’ve been into slingshots for 3 years now took many breaks but I am here again with a slingshot obsession wondering why the hell I can’t aim no matter what I do i watched videos copy them and can’t hit a target a few feet in front of me the only thing I can think of is that I’m left handed so maybe I shouldn’t be trying to shoot with my right hand does anyone have any tips?
