Any page that has labels (global or personal) will have them listed at the bottom of the page. Personal labels are only visible to the user that created them.
To view your personal labels,
Go to your name at the top of the page. (This is the 'User' menu. A dropdown list will appear when your cursor hovers over the 'User' menu.)
Select 'Labels' from the dropdown list. The 'Labels' view will open.
This will display all content with personal labels. You will also see a list of your personal labels along with the number of pages that contain the label. Click a link to see all content with that label.

Another way to get to your personal labels
If you are in a page that has personal labels, click on a label to go to the 'Labels' tab of your profile, where all pages in the space with that label will be listed.
