Kids track one or two tasks in their head. Adults need calendars and tools. Businesses work the same way: manual management fails once you have too many tasks. Invest in systems early to save time and money.
Kids keep a mental tab on their schedules. It works because they only have one or two things going at once. But the moment you have multiple things going on, you'll need to resort to a calendar. Your business, likewise, initially allows itself to be manually managed because there isn't that much going on. But sooner than later, you'll have many things going on and will need to invest in tools and systems. Don't delay these investments. They'll save you time and money.
