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.
For me it’s not like I don’t like music, but there are large stretches of time, where I do not care so much for it. I would guess that I haven’t actively choosen to hear music for weaks, possibly months, now. Obviously excluding the music you can’t avoid, like background music in movies and video games etc.
