A year in that job would also give yopu a safety net, time and money to plan, equip and network. Let the editors know this isn't just a lark
The danger of waiting is you could get in debt of get used to the steady income (golden handcuffs) or worse yet find your soulmate and fall in love. "You're quitting that good job for what?!?!"
I say go for it but do it smart. Good luck and send pictures.
