I’m worried about Mao’ist style short sighted policy, and if we cut off oil then it will destroy the poor in society who cant afford an increase in their heating and gas. Get the funding for nuclear so you have baseload power first, dont just cut off oil companies.

Shoot for a CCNP, and do the certs up to that. Networking is an easy one to get into as everybody else is doing cloud computing, devops, AI, or programming. If you dedicate your life to it like programmers do with side projects then you can get above them in salary as well, though its not necessary.
