J. Alexander CurtisAirTable is my favorite software tool. It allows you to build really powerful systems for your specific needs. There have been many tools I wish existedSee more in the world for my specific use cases. But with AirTable i have been able to create those organization tools myself for my own personal use. It really is powerful. It's like a spreadsheet, but mixed with other tools you love like calendars, trello, and more. Really awesome stuff! I use this tool DAILY.
