How about the music and entertainment industry? Any changes you noticed? They change daily. How about the oil business, the airlines and others? Okay, you have the point. Either the business, technology, people and economies change or something shifts. For those shifts any jobseeker or person who intends to have a long career must embrace change.
Now for a healthy outlook on your career path I recommend you:
1. Accept Change. To open a door to a new career jobseekers must focus on accepting change as reality. So look at the ways you have learned and enjoy learning. Express this in achievements and keywords in your resume and career marketing materials. Be ready to respond swiftly to the needs of corporations by offering different aspects of your background. No longer are resume just dry ways to demonstrate your employment during high school, college, through internships, military or other experiences.
