Go back to the beginning. Spend some time on all those easier climbs with overlaps, overhangs etc.. Wrap your mind around the experience of turning your back to the ground, not being able to see what's up above you, or reaching "blindly" over the lip, getting your hips positioned properly under the overhang and then as you move around. Or that commitment necessary to move that first foot over the lip. There are after all many easy overhang climbs for getting more comfortable with the experience. A couple of days early in the season will pay dividends later. Good luck and enjoy.
