Only one problem of having a job before returning to the Master school instead of studying right away is your age comparing to the classmates. You will feel that the youngsters have more progress than you and feel envious sometimes. However, other things are perfectly fine or even have significant advantages and I would recommend you to get a job before start your Master or even work and study at the same time, yet don’t work for too long since you will be addicted to the working life that is somehow more fun than studying. With this, it will teach you the ultimate time management lessen that you have to complete everything in time without missing any of them and this will be with you until the end of your life. Do not stay in the comfort zone. If you feel easy, make some useful challenges.
