Once in a while, we grew tired of routines and the problems we face everyday during our work. At some moment there are times that we want to say: "okay, i've had enough and I don't want to give a s#it about it anymore."
You needed a break. Just to clear up your mind and hopefully you'll be ready to perform after the break. If not, maybe you needed to find another job? (Hahaha) But hey, job is just a job, problem will always there, just not let it get inside your head. Know your limits and don't forget to have fun!
