I know it may sound strange, but one of the best suggestion i can contribute with is:
Take a glider rating or at laest some glider lessons.
Modern gliders have approaching speed of 55-60knots, weight 1500lbs and have a glider ratio with airspeed brakes
Out very close to any single with no engine and flap down, but they give you an amazing psychological advantage:
They have no engine :-)
You cannot go around an you must know how to always make the runway or alternatively the spot you decide to land.
Very soon the instructor teaches you the first rule: fly it never let the plane stall, kept the right speed.
No TROTTLE to compensate for misapproach.
You will find yourself very soon automatically spotting for place to land always and mentally computing the
Required altitude always, and feel a little bit confortable you can successfully manage a silent landing.
Have safe fly
