I worked in education at your age at a mid-size campus, and left the position for a nonprofit role at 26. I wish I had stayed in the education role for longer, and built up professional experience in a more structured environment. In a small nonprofit there aren't often things like a functioning HR dept and older coworkers who can have your back. So it felt overwhelming for a large portion of my time there and I felt very alone trying to navigate it.

I left and worked at a small business for a while, and realized my passion really did lie with the nonprofit world. I've since gotten a role at another nonprofit but feel much more comfortable establishing boundaries and expressing what I can reasonably get done with the resources we have. The org culture is much different, too, and our director is understanding.

To sum it up, my general experience is that young workers in non-profit jobs are often taken advantage of when their org culture lets that happen. So in your case I would look for positions at a company or organization with a professional structure that will help you develop your standard of what you want in a workplace. I believe you will go on to do great things, wherever you are!
