Whitehawk, GADS!! slow down. A couple days?? First learn the mechanics of the shot. Second, don't shoot to hit anything in the beginning. Just learn to shoot! And frankly it won't matter what aiming method you THINK you are using (instinctive, gap, whatever) after a couple days your shooting form won't allow effective aiming for all intents and purposes.
Checkout videos, books and this forum at length to get tips and ideas about shooting. Shoot often and regularly for a couple MONTHS then come back with your question. By shooting at a blank bale (NO TARGET) to catch your arrows, you will start to find that your arrows are grouping.
Once you develop groups ( at short range) then move back and work to get groups again. Short range = 5 or less yards, move back in 2 yard increments. Really not trying to discourage you, actually this will get you to where you want to be FASTER than any other method.
Learning to shoot the bow is not a "couple days" event. Patience grasshopper, keep it fun.
