Bernoullis are little invisible cute furry creatures that live on the leading edge of the wing. When you accelerate along the runway the wind tries to blow them off, so they grip the LE. The airflow over the LE is inclined upwards, so this pull lifts you into the air. As you go faster they have to pull harder to stay on, so you get more lift. When you pull back on the stick you increase the angle of the airflow, so you again get more lift. But be careful, because if you pull back too hard you can overpower them and they fall off, so you lose all your lift......
At least, that's what my wife thinks.
