Don't take your idea too seriously, either. The world will probably survive without your idea. Industry will probably survive without your idea. You may need it to survive, but no one else does. It is a mistake to think anything is made overnight except for baked goods and newspapers.
Nothing is as easy as it looks.
Everything takes longer than you think. Don't be afraid to make mistakes. If you don't try things, you won't fail, but you won't succeed either. Remember, if Edison had stopped at, say 30 filaments, we might still be in the dark. Permit nothing to affect the integrity of your mind.
