A person's true growth often happens when stepping out of their comfort zone and facing uncertainty and pressure. Reading helps people understand the rules of the world, action gives people the opportunity to change their position, and belief determines whether you're willing to take the first step when you can't see the results. Hard work doesn't guarantee success, but it's one of the few variables under your own control; emotions must be learned to be managed, choices must bear their consequences, persistence sometimes requires enduring solitude, but you also need to adjust direction when necessary. Grievances at work and setbacks in life are essentially costs of growth. Maturity isn't about never failing again, but rather being able to correct yourself and move forward after setback after setback.
