I had this problem, the solution I've ended up is...
Wunderlist (Android Task App) for non computer related things todo, stuff like shopping, meal prep, anything that doesn't involve sitting at a computer.
https://dynalist.io - Which was a revelation for me, by far the best way of organising my thoughts & planning.
Google Calendar - Used for long term reminders, events and general scheduling.
The most important thing I found was to offload everything into your head into tools that you trust and can do the job. I trust google calendar to remind me of stuff I've set it up to remind me, I trust wunderlist to remind me of the weekly stuff I need to do when I need to do it. Tiddlywiki will get me any of my old notes in seconds and dynalist let's me get thought processes out of my head into the computer better than anything else I've used.
