When an idea hits you, the longer you wait to act on it, the...
Less excited you'll be about it
Less likely you actually act on it
Less certain you'll be about it being a good idea as your subconscious mind will go to work second-guessing you
Less anyone else will support it (people will be eternally skeptical about ideas; we all believe action as it's self-evident)
Less likely your brain will deliver you another idea, seeing how disrespectful you were of this one
