As a Brit, but not a teacher, I would have 2 comments:
1. I believe that you can join the 2 sentences by converting the full stop in the middle to a colon, as they are 2 related concepts, as in ".... life: you .....".
2. I would have said: ".... into any shape .....".
Hope this helps
PS I, myself, hardly ever use the colon and would normally leave it as 2 sentences.
