People will love your product because you love it.
There will always be customers who would like to outgrow you and your product. Adding power-user features to satisfy some can intimidate others. Scaring away new customers is worse than losing old ones. We can say the same thing about new ideas. You become so enthusiastic about your new, brilliant idea that you decide to drop everything and begin pursuing it. Calm down. Think a while, and then if it’s worth it, act on it.
