I've chosen to use the todoist app for work, personal and creative goal tasks. And so far it's been helpful and keeps me on track throughout the day.
I enjoyed writing down to-do lists in journals and checking tasks off by hand. But I would forget the journals in random places or remember tasks when I didn't have the journal with me. Then sticky notes would come into the picture...This is why I picked todoist to start implementing first. I like how I can download the app on my cell, laptop and work computer so I can access my to-do lists anywhere.
