Focus on the positive (even if there's a negative). Have a running note of all the good things that have happened and what you've achieved so you can look back at where you've come from. It'll set you up nicely for when you need to update your resume or looking for behavioral answers for interviews.
While your life isn't always going to be rainbows ๐ and butterflies ๐ฆ, that's okay because there will always be some kind of positive in a negative, whether it's something you learned from that experience, what you discovered about yourself or even a partnership that formed. And when you're feeling the negatives too much, it'll a reminder of what an awesome person you are ๐!
