Thanks for the input. I haven't started testing any tools out. I have been using Google Keep and Google calender for a few months now. I don't really have a like structure to how I manage tasks. Just write something down and put in a reminder rarely. Mostly they happen in the head which is why I forget to do a lot of things. Just like you said, I too use Keep and Calender only because I can access them on my phone and laptop and its the same login across these programs.
The other day I was watching a video from David Allen about capturing everything, writing them down somewhere and then organising them into reminders. Haven't tried that method out yet but it looks interesting.
