I've been playing guitar for 40 years. I haven't improved much in all that time. That's an exaggeration because I do know how to do it better now than I did when I first started. But I'm still not very good. I know how to hit the right bass string when doing chords, but my whole manner is pretty boring.
Essentially I'm stuck at the few chords I've known all these years. And I have a hard time branching out to learn anything different.
One of the chords -- chord groups? -- that I don't know how to do very well is the whole bunch with B flat, E flat, those. I was just trying them again on a song I need to do. I look at chords for a song online and -- Doh! -- it's one of those chords! To me they don't sound good at all, so I'm always wondering if it's just me.
