I've moved from one app/platform/day-planner over the years and never been completely satisfied. I currently have a lot of goals and projects on the go and I was feeling so overwhelmed I was having trouble achieving progress in any of them.
I saw Mind Matrix, took a look at Notion, thought I'd give it a go. I spent 10 hours bringing in all my projects into Mind Matrix. After I got a handle on the mechanics I was able to immediately start building out my goals with the underlying projects, and those projects with the underlying tasks. Once I had those out of my head I could now start the actual work and discover all the subsequent tasks that need to be scheduled to complete the project.
I'm using it everyday. I have it on my phone to quickly capture tasks as they pop up in my mind. At the end of the day I'm planning the next day. Nothing is getting lost.
I'm impressed and I'm sure I'm only using a fraction of Mind Matrix capability. Worth every penny.
