And you should purge it occasionally. With Trello, I use the "card aging" feature to see which things haven't been updated or moved recently. Each week, I spend five minutes skimming through the cards, making sure there are due dates if applicable. At the end of each month, I spend closer to 20 minutes and look at each card and ask "is this still relevant?" and give it a simple yes/no. If it's "no" I delete it immediately. Those never-ending tasks and wish lists simply go away. It's not like I was going to do them anyway and it's less junk on the list. I do the same for meetings. None of my recurring meetings/tasks extend past December 31st. After the January 1st, I double check to see which ones I really need and are still relevant and recreate those. The others are already done.
