It’s worth saying that applying for things can also yield some benefits. I definitely became a better writer through the various work tests I did when I was applying to lots of training programs. I also got some nice feedback (props to CLR especially!) and the experience helped me to better understand what different orgs & people are working on. I also got a clearer idea of my career aspirations.
This is assuming you get through the very first round and get to do some test tasks though...
The soundness of this advice depends a bit on what career path you want to pursue, though. If you want to do some lobbying or policy advocacy, it’s pretty difficult to “just get to work” if you don’t have the right network, skill set, and credentials. And working in that area without knowing what you’re doing can also be quite harmful.
