Are you an impending high school graduate and fretting about what major to take? Are you a fresh college graduate and have no idea which job to try out? Are you already working but too conflicted about what you do?

Bullhorn's Chief People Officer, Kim Castelda, may have just the sage advice to help you out. She wrote an article on Fortune about three key things to remember.

Test the waters.

One way to know what career you are suited for is to dip a toe in the waters. How do you know you are going to like it if you haven't tried it out?

Castelda writes that gaining experience in the field you are interested in will help you make a decision in regards to the intended career. You can do this by researching, talking to people who have the jobs you would like for yourself. 

The good thing about testing the waters is that if you come to realize that that field is not for you, you haven't gone too far deep to get out. You can shift to another field, try out another career, and hopefully find one that works.

Be yourself.

Success is not dependent on how many mistakes you managed to avoid or how perfect you are able to do your job, says Castelda. Do not try to be perfect but rather be yourself.

When you are yourself, Castelda writes that the pieces of your career puzzle will fall into place. You will succeed because you are learning from your mistakes, doing what you are passionate about, and interested in your field.

Your passion will not just fuel yourself but those around you and your customers as well.

Be authentic.

Be honest with yourself. When you find yourself not looking forward to going to work, uninterested in new projects or tasks, then it might be time to change jobs, writes Castelda.
