Actions to take for a career change towards EA (advice needed)

Thanks for the advice!

Yes, I agree. Looking for a job that has the biggest impact is a better goal. There are a lot of helpful questions here for me to go away and think about.

Seems quite a daunting process so far, many jobs I have applied for have come back with responses of "700 people applied for these 5 positions" etc. 

Can either of you point me in the direction of useful job boards apart from 80k hours?
