As scary as it may be to start anew, I hope you're also really excited! I've changed careers twice now (maybe three times actually) since graduating college in 2010. I think the best thing you can do is take a real step back and think long and hard about what your personal values are. What exactly are you trying to optimize for? What energizes you? What drains you?

I try to do this exercise at least once a year. It helps me to distill what it is exactly I'm working towards. Your values will change over the course of your life and it's important to continuously re-evaluate what matters to you now. With your values in mind, you can then make sure that your behaviors are in line with what you care about most. Having a general "north star" will help you evaluate different options as you continue to brainstorm and think about what you want to do next.

Good luck! And congratulations! :D
