In my 30s here too! Very encouraging to hear from others doing the same! Thank you!
Worries:
Rejection, making no real progress in life, except possibly starting the whole process over again.
Excitement:
The possibility of getting in and moving ahead in career/life, discovering the fully funded programs that are available, which is what encourages me to try in the first place, and learning that trying all of this in your 30s is actually a good thing by most accounts!!
Positive vibes and thoughts to everyone!
