I began learning Blender at school a few weeks ago. In order to develop a foundational set of skills, I had to model a total of six objects. These objects were made using box-modeling. Below you can see all the objects I've modeled over the last 3 weeks.

Working with Blender was quite scary to me at first. Finding the most efficient way to make objects and learning all the shortcuts were the two things I found the most difficult to master. However, after working on the first couple models, I felt more at ease and started to love experimenting in Blender.
