Fly as often as possible, twice a week is a good rule of thumb. If less than once a week you start rusting, and spend time and money on re-learning stuff.
Be prepared for every lesson ! Go mentally through every detail of the next flight.
Also, don't get too frustrated, you will at times feel you're not going forward, and even going backwards e.g. with your landings. Keep going, suddently it all comes together.
