can do a bind like
bind mouse1 "+toggle cl_dummy_hammer 1 0"
bind mouse2 "+hook; +toggle cl_dummy_copy_moves 0 1"
it will disable copy moves when u hook for no copy hook but i idk how it will work ingame

from there you should keep playing moderate until you can look at maps like grandma and stronghold and 100% think "that looks easy, i can do that"
