Sometimes, things seem impossible until you give them a real shot! Sleeping in a Sukkah for a week sounds impossible, but there are people worldwide who do it each year. The first and second days may be difficult, but by the third day, you’re getting used to it, and you’re using your experiences from the previous days to improve your remaining days. 

Just like a healthy lifestyle, repeat, learn from each day’s experiences, and see how something you thought to be impossible is in fact POSSIBLE.
