Yes you can wait a while to do something like this but a lot can happen in the intervening years - marriage, kids, house, medical issues, aging parents, etc that can hinder your ability to take time off and explore things you are interested in. If you've ever wanted to try something like this I would suggesting doing it young.

I'm currently doing a smaller version of what Joshua describes and had to get approval from manager to get unpaid time off from work. His response: I wish I could have done the same thing. He later even admitted that he was living vicariously through me!

That being said, do save as much as you can as early as you can. Just don't let saving get in the way of living your life
