Depend on the traffic situation, you don’t need to taxi all the way to the beginning of the runway. You can taxi into position as normal takeoff.

Pump brake a couple of time before apply full power to prevent the airplane from moving.

Try not to chase the airspeed indicator needle. Remember, airspeed indicator has lag. If you chase, airspeed may be too slow or too fast.

Again, don’t chase the needle of airspeed indicator. Look at the pitch attitude. Make small change in the pitch. You still want to climb. Don’t descend.

Check "positive rate of climb" before retract. Once you retract the flap, pitch will change. Be prepare for that.
