If your idea is rejected don't be upset. It's important to be resilient and resistant to hearing words like NO and this is a stupid idea. I say this because today I learned about the German invesntor George Ohm who created the world famous "Ohm's law" was rejected by the German scientific & education community for over a decade after Georg Ohm published his research. So keep on pushing if it makes sense. If you have an idea that is not true or is a crap shoot then maybe it is best to try something else but in the case of Ohm's Law George knew the science and it all made sense but the ignorance and stupidity of others stopped him from being a proven success for many years.
