Google Calendar is one of the best resources out there to organize your life. With it, you can not only set events but do other fun things such as add descriptions, change the color, add a place, decide when to send the notification, and even add conferencing on something such as Google Hangouts. However, that's not the only thing you can do. You can also add reminders and mark them as done afterward. Google will continue to remind you if you don't label them as done, which is great if you realize that you haven't done something that you were supposed to do yesterday. With some other great features such adding goals you want to accomplish, notes you want to jot down in Keep, and adding lists of tasks in Tasks, Google Calendar was a great way for me to get my life back on track.
