A *medical device is "an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is: recognized in the official National Formulary, or the United
States Pharmacopoeia, or any supplement to them, intended for use in the diagnosis of disease or other conditions,
or in the cure, mitigation, treatment, or prevention of disease, in man or other animals, or
intended to affect the structure or any function of the body of man or other animals, and which does not achieve any of its primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its primary intended purposes."

Early Years (1st couple of years out of school) Be a sponge – learn as much as you can! Set daily / weekly goals for yourself (i.e. complete task X by
Friday) & prioritize based on importance Put your personal life “on hold” when you are working Be clear on your manager’s expectations and understand what is
important to him/her Be pro-active and do more than what is expected Develop good working relations with the team you are working
with Find a mentor (engineer) and meet semi-regularly to get input
and feedback Don’t be afraid to make a mistake… you’ll learn from it Force yourself to do the things that are hard for you Find out what you really like to do
