Travel internationally
Right now, if you had a good career and made a bit of money .... you have the right amount of resources and age.
Any younger and you'd have no time and probably no money.
Any older and traveling is no longer enjoyable.
My wife and I, we have no kids, did a lot of traveling in our 20s and 30s. We're not wealthy and did a lot of shoestring dirt cheap budget traveling. It's amazing how far you can go on not much money.
Towards the end of our running around about ten years ago, we discovered cruises. You never pay full price and you just book last minute and you can find deals discounted 40, 50 even 70% off because the company just wants to fill every room on a ship.
Go to vacationstogo.com .... sign to a basic account and look up their last minute deals. I'm not a salesman or marketer, my wife and I found this site years ago and we tell everyone about it.
You'll find last minute deals there for cruises that originally cost $10,000 discounted down to $2,000 $3,000 and sometimes even less.
