My Notes
One of the best articles I have read on Todo lists and it has some great reference links too!
Do give it a read.
It’s not always about finding the best system and implementing for yourself. Different things work for different people. The blog above has examples of different people using todo lists in different ways. Experiment and find what works for you. Don’t generalize yourself!
