Is there still hope for me?

Hi everybody! I’ve been a NEET for almost 7 years (since age 25 to now that I’m almost 32). I am enrolled in a program which insert people on the job market (I survived thanks to disability in these years). My plan is to work a couple of years in order to than go back to school to become a kindergarten teacher. Do you think I can do it? Is it possible? Is there still hope for me or, since I have a 7 year gap on my resume, I will never stand a chance and need to settle for more humble jobs? Not that I have anything against them, I just have a dream. What do you think?
