My one track mind

Recently I've developed a bad habit of not reassessing my position, to see if I have a better move or plan. Instead I am following my chosen plan fairly robotically, and then find out afterwards that I have missed a number of quicker wins. I do try and make sure I am not missing any good moves by my opponent, but annoyingly, I don't apply this discipline to myself.
Case in poit: my last round game from the Belconnen Club Championship. I thought I had played a nice smooth game, where I kept the position under control, didn't rush my attack, and found the simplest path to victory. In reality I missed the win of a pawn on move 27, a win of a rook(!) 2 moves later, a forced mate  on move 30, and finally, a totally winning combination on move 32. Instead I followed the plan I had previously chosen, where if I calculated correctly, I would be a pawn up in a queen and pawn ending!
