It is always important to invest time in yourself. Learning something new is a great way to spend that time. Whether you learn or take up a new hobby, or go back to school for additional training seeking ways to hone and improve your skills will help you grow professionally. Sure, training in any area may require some expense and definitely a significant amount of time but think of it as an investment. This investment is invaluable, and could help you become more employable, or prove to your employer that you are original.
