One of the things that I think is important is for you to look forward in life. Look forward in your career to the professional that you want to be. Hopefully this is a goal you get closer to, but never reach as you strive to always be better.
Even if you change directions, for example, for me moving from a software programmer to an administrator to a DBA to a manager, you are striviing forward in a new direction. It’s fine as long as you strive and work to improve.
However does your resume stretch you a little? Does it show your potential future employer were you want to go?
A little hint: it should. Part of your resume is what you want from a job (or client), and how your past supports you moving in that direction. Emphasizing this, highlighting this early in your resume, does a few things.
First, this allows the employer and you to quickly see if there is a good fit. If the employer needs someone to maintain old ASP technology and you are looking forward to data science, or vice versa, this probably won’t work for long. There’s nothing wrong with deciding this is a bad fit. It can save you from thinking you will find a long term position when you’ll be quickly bored.
Of course, this also gives the employer the chance to think about whether they want a short term fix for something.
The second thing is that you get the chance to drive yourself forward with the things you choose to emphasize about yourself. You achieve some focus here.
If you use it. That’s the hard part, but with some effort on your part, you can focus your efforts in small ways to drive your career actively.
