Have a will for it and be ready to do continuous traveling and also do loads of work on your travel itinerary and post travel things to earn money along it
I think First thing is you should have passion for the travel because it's not just the beautiful mountains or a calming beach..it takes a lot of effort to plan all this..if you are accepting all Pros & Cons with a full beam smile you are ready for this...
Leave the job and get on a solo trip for 2 months with zero contact to your past life, just roam around and get to know if this is the right decision made!
