There comes a point when the novelty wears off and monotony sets in. 

You go to work, you perform the same procedures over and over, you get home late, eat leftovers straight out of the fridge, go to sleep. 

Then you wake up and do it all over again. 

The second you get lulled into the routine, that's when it happens. 

That's when you 

 changed your life. 

helped you see the kind of person you wanna be.
