I recently removed my personal todo list.

I found that it was usually a way to not think about the different issues/projets I had in mind. Removing the todo list forced me to remember the list, to think about possible solutions or related task I wanted to do.

I was really, really productive for few weeks...

Unfortunately, I quickly fallback to my old habits of listing todo... Simply because I don't give myself proper time to think about what I want to do.
