Ideas are not todos
Your todo board should not be the place where you store everything you can imagine. You will never get to that point in time where you will hit that last ticket. It will get too much.
Great ideas will never leave you the same way bugs do. Store your ideas far away from your todos.
One problem we have today is that our backlog fills up with old ideas and urgencies that never resurface. They still are there clogging our brains both virtual and real, reminding us that we have enough to do. We don’t need anything new.
If the ideas are your own you should store them somewhere in a box or in a folder. Fill it up as you do with old memories. But where you work and plan should be fairly tidy.
Where and when you ideate, you can open that box and pour it all out.
So remove all the tickets in your backlog that you have not looked at for 3 months. Bring them back when you need to plan and look for things that might inspire you. But don’t let them lead you.
