What systems do you have in place to keep yourself organized?

"I keep myself organized by utilizing google calendar and plugging in all meetings, phone calls, appointments, deadlines, and important dates. At the beginning of each week and each morning, I look at my calendar and create a daily to-do list in order to prioritize tasks and make progress on work. On top of that, I make sure to keep all documentation, contracts, and invoices tracked and organized to ensure I can always access what I need."
