“When researchers looked at the ability to persist in various domains—from cycling to math to calling for donations—one factor kept popping up. Those who persisted had different goals. They weren’t driven by fear, or guilt, or pressure. They didn’t keep working in pursuit of money. They were pursuing a goal because it aligned with who they were and brought them enjoyment and contentment. They were choosing to do the work, not being forced to. And they were having more success.”
