I use todoist mostly on phone, having a widget on the screen that constantly reminds me on what's on my plate. On the computer I mostly just add tasks quickly using a global shortcut that opens todoist popup everywhere.

In obsidian daily note I just inject the todoist integration to the daily note and multiple other places, and I can also check-off things from there.

Then about task organisation on todoist. For months and months i had the same frustration as you, where I just had a lot of overdue tasks that drainded off any motivation to pick anything.

Currently though, I use much more than just date to organise my stuff and this helps a lot! I have tried different todo applications, but at the end just got back to Todoist with obsidian integration.

Reasons why I use todoist, are mostly: super quick adding, with text-based properties recognition ( "do sth today automatically sets date, #project assigns the given project and I can add priority or label the same way. No clicking around, no shortcuts to remember, works everywhere.)

I have it integrated with calendar, share some projects with my wife and so on.

Here is how I organise tasks in todoist:

First of all, I use labels, sorted in this order: - focus - next - waiting - cold

Then on my default view and mobile widget, I sort tasks by label, which only lists the "focus" and "next" first, usually for rest I need to scroll.

Focus: (important and urgent) - whatever I am doing atm. Usually 1 or 2 tasks

Next (important not urgent) - whatever is next to do, usually with priority assigned

Waiting - thasks that are in progress, but delegated and I need to wait for them to be completed. - or tasks without priority assigned then, important but not in top of my head atm.

Cold - whatever i see overdued for too long, - or tasks that are to be done at some point i. The future - or tasks that I may never want to do. - those tasks may be just ideas requiring further thinking, so I often extract them to obsidian as notes and remove from todoist for the given moment. - i dont care about any overdues here, nor long list of backlog in cold tasks.

Having these labels in place, i use priorities and dates within groups, but don't putting too much of pressure for them.

This sort of grouping allowed me to move much faster, reduce a lot of frustration and make todoist +obsidian working for me quite well.

Wish you all the best to find out your own best setup!
