Missing components?

Dear Members, I am new to CRM and Dynamics. According to LearningLabs videos and other material, I should be seeing an area headed "My CRM", an area headed "Workplace", and a pane headed "Activities" yet I can locate none of these. I have "Relationships" and "Settings". Do I have an incomplete deployment of the CRM or could anyone point me to where/when I should be able to see the 'missing' components? Regards.
