When I was 13 years old, I realized the popular kids were not always happy – they just looked really happy when they were busy hanging out with friends (which was often, but not always). When they went home and found themselves alone, they suffered the same withdrawal that I did when they thought too hard about it (some hyper-social kids are never comfortable alone and have worse withdrawals than anyone else). We find ourselves at our lowest points at home left alone with nothing but our thoughts. In rough patches, these lulls sap our energy, optimism, and confidence. Loneliness cripples us.
The popular kids taught me early on that staying busy and surrounding yourself with good people dramatically increases your positive energy and quality of life. Like a shark, you are happier if you keep moving. Stay active, keep friends close, and only stop to reflect if you dare. Before long, you might even become the popular kid.
