This will keep you from ever doing them.
Better to say “not yet”…things take time…barre chords are not easy and it might take a couple years (or so) to build the dexterity & strength to pull them off.
I’ve been doing things that were “impossible” for me in the beginning for forty years now on several different instruments as well in other things in life.
Was it frustrating? you bet
did I think I might never get it? many times
did I give up? no
I’ve worked on breaks to songs that took me over two years to get right. .
Some things take a long time to get…but “can’t” & “Never” need to leave your vocabulary
Sorry if this sounds a bit harsh…it isn’t meant that way…but a positive frame of mind and a “can do (eventually)” attitude are really necessary to get over the difficult humps we run into in life as well as in music.
I believe you can do them eventually!
