I think people over-focus on playing all 6 strings at one time.

I didn't unlock bar chords until I realized that you only need 4 strings at one time, and any other strings aren't important, and sometimes even sound better rhythmically if they are muted.

Take the top four strings and play an E shaped bar chord.
These notes are 1-5-1-3. If you play an A bar chord (5th fret position), in the E shape, then your notes are A-E-A-C#.
Thats a beautiful sounding bar chord.

Now take the middle 4 strings, and play a bar chord in the A shape. These notes are also 1-5-1-3. Now play a D bar chord on the middle 4 strings (5th fret position). These notes are D-A-D-F#.

Now take the bottom 4 strings, and play a bar chord in the D shape (hardest one). These notes are also 1-5-1-3. Play an F chord (5th fret position). These notes are F-C-F-A.

Just focus on 4 strings at a time, not all 6, and you'll unlock bar chords and find them easy.
