As attractive as the offer might be, don't give in to the temptation. Entertainment is good, but not when it takes away your productivity. You need to know when to do what and why. You need to know what is important to do when.

Refreshing your mind is a good idea and it is important, and the timing of such is when you really need it. Like when you have been working a lot and you are tired or maybe stressed out. Entertainment is there for you.

When you are bored or when you are behind schedule, the the opposite is beneficial. You need to work. You need to find something productive to do with your time.
