In many ways, starting and growing a business is a lot like hitting puberty. Decisions get made erratically, unexpected periods of growth and change take place, you’ll often find yourself getting angry for no reason, and will often need to depend on others as you fight your way through unknown territory. But, you aren’t a stroppy teenager (unless you’re a teen wunderkind reading this, in which case we apologise). As an adult running a business, you have a sense of perspective teenagers do not.
