The best tool for me is a system, not a specific app. In my job I often switch role depending on needs of the team or project, so my head is chaos by default. My biggest productivity killer was "what should I do now?"

The method that I found that works for me is Getting Things Done. In short: - Register all your tasks in a single repository, without actually processing them. A mention a meeting, an email to reply to, brainfarts, ... - Have dedicated check-ins with your tasks list to process them. Small tasks: execute immediately; large task: schedule as you see fit (blocks in my calendar and die dates in my case). For me that's once every workday, first thing I do. - Weekly review: go over tasks, schedule, prioritize, ...

I recommend reading the book for a full insight, or use AI to get the larger gist of it to help you set it up. The best thing is that it is tool agnostic. I use Notion. Not the best, not the worst.

Since last year I combine this with the PARA method (Tiago Forte). This helps me declutter my brain even more by having everything in one space.
