I get your points. However, when I tried to have my to-do lists on paper, I just kept on losing them, so it was pointless. I travel a lot, so I don’t want to be bothered with lots of sheets of papers all over my luggage. Don’t get me wrong – I’m not saying paper lists aren’t good, it’s just not a solution for me. I manage my tasks using Kanban Tool ( https://kanbantool.com/ ) and I find it very convenient that I can have all of them online, every time I need them.
