The skills and behaviors that you need to succeed at work are different from those you need to succeed in your personal life.
Maurinko [17]

I'm not sure if this is a true or false question but if so then the answer is true. The skills and behavior you need to succeed at work will be different, there will be some similarities like organization, time management and effective communication but you also need skills like team work, knowledge of your profession, presentation skills, report writing, data compiling for example. You will also need to know how to talk to people in a professional manner, how to present yourself as hard working and how to dress appropriately.
