Advice
Know the reason you are working for. Also, know what you are working for. I recommend that if you do not find yourself in an uncomfortable financial situation, do not work excessively. Working a job teaches you time management, responsibility, and many more things. Please do not forget about who you are and things that make you a person. 8 hours is the typical amount of time for a shift. Find time to focus on your interests, goals, etc., outside of work.
