Even though you have ideas, they don't work!

This reminds me of the famous quote from Thomas Edison when asked about how many failures he had when trying to make the first light bulb. His response was "I have not failed 1,000 times. I have successfully discovered 1,000 ways not to make a lightbulb". That is the thing unless you try you never know what the outcome is and as long as you learn from the failures then in fact they haven't really been failures as you have learned something which you can can use in your next entreprneurial endeavour. Just remember this "The three great essentials to achieve anything worth while are: Hard Work, Stick-to-itiveness and Common Sense"

If I were you, I'd try to learn as much as I could from my failures. I bet some of your ideas are good, it just that maybe they were not executed properly or they just need more help. I get ideas, too, but they usually are not feasable for me. I've even had some ideas that later were made into "as seen on tv" type stuff (but I never persued the idea, just saw someone else get rich off of it). Anyway, goog luck to you.
