The key as you outlined it is to never give up. If something is not working, quit doing it and try something new. Do so until it works. Then, keep at it to imporve or to stay on top of changes as the business world is in constant motion.
Lastly, remember growing a business to profitability takes time and hard work - period.
I completely agree with you, one should not keep trying or following one technique if it is not giving any returns. Better, change the technique and try for something new.
