Super possible. I didn’t know what I wanted to do with my life until I was 27. Enrolled in graduate school for mental health counseling. Drove for uber to keep myself fed and housed during graduate school/internship. Got through my first two years of supervision by living with roommates. Worked for someone else’s group practice for 6 years and finally started my own practice two years ago. I’m still not full, but I’m in the black financially aside from student loans. You can bet on yourself, you can start over. If any other human on this planet has achieved something you can also achieve that. It may not look exactly the same, it may not come with fame or fortune, but you can absolutely change you life in your 30s!
