How do I get a calendar of my own work to show?

Select the Calendars option at the top. 

Select + New Calendar

Give it a name and using the filters i have selected, (Be sure to Select all Folders and/or Projects you want to see the tasks from) you should be able to create a Calendar containing only your own tasks. 

I hope this is what you are looking for. If not, try the Classic option and use the filters. :D

If that still does not work, let me know, we'll dig in some more. 

Quick note. When i made this for myself, i forgot to check the Status of All Active, so everything showed up. To Edit a Calendar, hover over the name of it, then click on the 3 ..., select Settings and Sharing. This is also how you delete a calendar if you need to.
