Before you even consider starting out on your career journey, consider where you want to go. You don't have to be fixed, but I have seen people just simply following a path and end up being sad for don't ending up where they wanted to be.
This is your chance to dream, think big and be wild in your approach - if you get close to those wishes you may be further along than the alternative smaller successes.
When you start going deep, think about the connection between your inner desires and your rational goals.
They have to match - to ensure you feel fulfilled with your professional life. Setting goals takes a lot of time and effort, don't rush it but it is important to any successful journey.
