You will be spending a lot of time at your job so I hope you really like what you are doing. So if you do, be excited about what your opportunities are and how you can make a difference. It is important to not only say you are passionate but to show it. Let your energy and excitement shine through in your interactions and projects. It can be contagious and a positive force. But I would say if you are not energized by what you are doing, if you are not excited about the opportunities and challenges ahead of you on your current path, think about pursing another path. Life is too short to not be jazzed about what you are doing!
