You don’t have to be super rich or be a trust-fund baby to travel around the world for months. I find the general estimates for a more frugal world-traveling for a year are $20.000 to $30.000. This is obviously not doable if you really live paycheck to paycheck, but if you have a relatively well-paying job and live very frugal it is not impossible to save this amount of money. Also there is the more irresponsible solution of taking on debt.
