How to stop making blunders during your chess game

The middlegame looked easy, you had a clear strategy and detailed plan, all the tactics seemed to work in your favour, you slowly began tightening the noose. The victim already had a look of dread and disgust at the sight of the imminent siege. Victory was almost certain.
