Your ideas don't matter too much if you never do anything about them. You can go through life saying "I will do this" and adding the idea to a "someday" list several pages long. You can also go through life saying "I did do this." Both the idea and its execution are necessary and both matter.
People say the first step is always the hardest. I'm not convinced I agree. I find that the subsequent steps after an idea's launch are much more difficult, but the most difficult is when things seem to be at a plateau. Keep going anyway.
You don't get credit because you had an idea, you get credit because you kept it alive and did something with it.
