Hi Razano... I think that if you are giving each one of these jobs its due then it doesnt really matter how you get the job done. Having said that ... if a task does require a high level of concentration and focus you then need to disassociate from any other tasks and get it done.
To help with that you may want to remove any distractions from around you so that you are not inavertly taken away from what you need to do.
A basic Time managemnt princple is to list your tasks, and prioratize them and go from there. Maybe having a to do list every day will help you with you juggling act?
