If you simplify your process using one fermentor only as so many brewers have, you will NEVER be done in 3 days. Some debate the benefits of secondary, but for new brewers obsessing over airlocks primary only is definitely the way to go. It helps you learn the first and most important brewing lesson, PATIENCE!!!!
A quick note on airlocks- they provide some evidence of what's going on but are NOT proof of fermentation or lack thereof....
