Piece activity and focus important in Kings Indian game

This is my second post of a game I played late last year.  I felt that after about move 21 with the Knight exchange for the Bishop I was getting steadily worse in the game. My Queen and other minor pieces didn't have much scope nor activity which looking like a loss. My Queen finally did get out and with some counter activity and time pressure my opponent blundered which turned the game in my favor.

I appreciate any comments that you might have. Thanks.
