I'm new to this channel so be easy on me please.  I've been on this earth 72 years and have been playing AT guitar for about 20 years a with no direction.  Just fiddling around.  I'm trying to gain some direction now and have my chords and changes down pretty smooth, with 1 exception. Trying to get a change from C to F barre and G to F barre, and probably any other open chord to F barre.  I know the F barre, it's been my nemesis for a couple years now.  I've tried about all I can think of, repetition, rolling my index finger around, etc. and it still sounds like s$&t !  Every now and then one good one will sneak out.  I have a fairly good amount of arthritis in my hands but I play thru it as long as I can.  Any suggestions that may help me will be much appreciated.  Thanks all, for listening.
