Good ideas are everywhere

Novice entrepreneurs tend to see opportunities everywhere and, if they have the resources, feel tempted to expand production too soon, or jump into too many new market segments all at once. Especially if they have some initial success, it is easy to feel prescient (i.e. believe they can predict the future) as well as omnipotent (i.e. believe they are invincible). But good ideas are often a lot less glamorous than that.
