After years, it can get you bored, especially for the software business and cubical workplace, and iterations way of work ..... sometimes dummy tasks or intended dummy assignations by superiors that do not quite understand your potentials
and Worst of all the billing procedure for every task, that is handled by pre mature management, making it suffocating for developers / testers to innovate ...... most of the time you need to innovate for free and on your own risk ...... which wastes your personal time, and with time, you realize you have not learned enough (Actually may have lost what you already knew before you got here)
