A less-known hack to perform wonderfully at work: 

Have meaningful relationships outside of work.

Hike with your college friends.
Shopping with your cousins.
Go to a park with your family.
Concert with your former colleagues.
Or even a heritage walk in nature just by yourself. 

Everything that appears leisure and time away from work actually builds you up to work more effectively when you get back to work. 

Which is why you must actively build it into your weeks.
Which is what I do and block in my calendar as well.
Which is what you must go for, this weekend.

Time wasted is not productivity wasted, if it is something that genuinely fills you up.
