I organize literally my entire life between Trello, Google Docs and Google Calendar.

Trello handles strategic planning and todos i.e. "Learn Spanish , Get new job" and a separate board handles smaller more operations stuff like "buy an electric toothbrush" or "finish reading system design books"

I even designed a system with trello custom fields, webhooks and an aws lambda that will automatically sort the task buy some weights I can assign. (Just numbers for urgency, impact, and effort)

I use Google Calendar for time sensitive todos. Stuff that is or needs to happen on a specific day.

And if the calendar event description gets too long i make a trello card for it.

Google Docs I use for long form content like keeping track of my own understanding and research of modern software architecture, techincal interviewing, or competitive fighting gaming.
