This is good advice. The other point I'd make is: when you do start the travelling, ease into it so you get comfortable working from a foreign country, dealing with cell roaming, WiFi, local postal system, co-location spaces etc etc. By ease into it, I mean start with 1 month in a super-backpacker-friendly place like Chiang Mai Thailand, Quito Ecuador, Antigua Guatemala. That approach will massively reduce the stress of starting out.
