Some suggestions
DO
Do remember that since the majority of fatal stall/spin accidents occur at low altitudes, from which recovery is unlikely, prevention essential.
Do practice stalls or approaches to stalls at an appropriate and safe altitude and only when you are competent. If it's been awhile, take an experienced CFI with you.
Do practice spins only with an instructor who is current and only in a properly maintained and approved aircraft. In some cases a parachute may be required.
Do fly at a safe altitude above the ground so that you won't be surprised by terrain, wires, or towers that would require a quick pull up and a probable stall.
Do remember that turns, vertical (pull ups) or horizontal, load the wings and will increase the stall speed, sometimes dramatically.
DON'T
Don't explore the corners of the flight envelope close to the ground.
Don't exceed 30 degrees of bank in the traffic pattern.
Don't follow another aircraft in the pattern too closely. If you cannot maintain a safe airspeed (safe AOA) - go around.
Don't buzz or otherwise show off with any aircraft. You don't need to - as a pilot you belong to a special group - less than one third of one percent of the U.S. adult population is certificated to fly
