The simple rule that always works is: Unload the small wheel.
For a taildragger, that is stick forward to unload the tailwheel.
For a trike, that is stick backwards to unload the nose wheel.
Then as airspeed increases, and you get "feel" in stick and rudder pedals that the air is "biting", then you can start to "fly" the aircraft to take of.
Most think that "flying" starts when the wheels leave the ground and stops when the wheels touch the ground.
That is why so many "modern" pilots get in trouble when they convert to taildraggers.
