This lecture I find a bit difficult to follow - but getting there slowly. (how do one remember all these things) 
Don’t give up!
You will learn by repetition. Keep working on you models.
Lots and lots of times I had the thought “I have learned this somewhere, but where, but how to start?”, and “Where’s that option to …”.
The funny thing is, you now know where to look for and how its named. Then you can search for it on the internet for more info. Lots of Blender things will become more natural, when you spend more time on project.
Also you get more confident to do things.
See you in the next lecture…
