I need this to be so simple. And struggle to now what to include and what to leave out. Too basic and they seem pointless. Too detailed and they seem to take up too much time I could be focusing on other things… any suggestions on how to prioritise and discriminate between tasks to include and task to accept as given.

You should classify your to do list between urgent and important, urgent but not that important, important but not urgent, neither urgent nor important. You prioritize the first type and give it specific time slots. The second type is to be done during the day, when you find the time. The third one should be checked once every two days or so. The fourth, once a week at least. Hope you find it useful!
