No matter what your profession is, keeping a balance between your professional and personal life is very important. For employers work will always be more important than his employees. In order to succeed, yes, it is true that one needs to work really hard but then again maintaining a balance is way too important. Working all day long will only result into exhaustion. Also, not working at all will result into a job loss due to which you won’t have to maintain a balance. Out of both, I am sure you do not want to end up in any of the situations so ensuring that you try to keep a work life balance as a designer is very important.
