The section describes the planning process for my trip (what I am doing at the moment).
When going on a complex trip, you need to:
decide when and where you're going
decide on the types of activities you are likely to engage in
understand the climate
understand any medical risks
Then, you need to take the following actions:
arrange finances (have enough saved up or work as you go)
select and acquire suitable equipment (depends on activities, climate, etc.)
prepare for medical risks (vaccinations, medications)
prepare for financial risks (medical, property insurance)
prepare legal, property, and financial matters (car, home, will, taxes, pets, bill payment, etc.)
get travel documents (passport, visas, driving permit, etc.)
arrange transport (at least to get you started)
That seems like most of what goes into this sort of thing. I'm sure I left something out.
