Below are various resources that I have found useful over the years. If you have some post a comment below and it might make it on the list.
Relax Channel – If you like having background noise while working but don’t want lyrics and/or signing in it, this is a super awesome resource.
Todoist – This is hands down the best to do app and task tracker out there. I’ve tried various other tools and always found myself coming back to this one.
