Write down all your ideas and publish them on vixra.org as well as on this site. Do not be concerned if you feel the idea is "rubbish". Self doubt gets the best of all of us sometimes, so be careful to not let it get in the way of discovery/insight. I know for a fact many of my ideas are nonsense, this does not mean I will not publish them though. Look for yourself: http://vixra.org/author/jeffrey_joseph_wolynski
