I love side projects. They are what wake me up at night with excitement; they are what causes light bulbs to flash on inside my brain while walking my dog; they are what motivate me when all other motivation is lost; they are the distraction from my worries; they are a fundamental part of who I am as a developer; and they are an integral part to the success of so many of this world’s greatest developers and business owners.
Be responsible. Noted.
