You shouldn't. If anything, you have an implementation to show around. That alone puts you ahead of a lot of people who are with ideas only. "With their mouth people build castles" people say in my country. You've actually built a least one (not just with your mount). Like someone else said: Maybe working freelance for a while will help. You will see how you can augment other people's problems with your ideas. New stuff will arise in the process. Do not give up. As an example WD-40 was the 40th test people say. You at least have to try 38 more times.
