The problem with having 50k in saving is that it looks like a lot of money but once it becomes your only source of income, it will quickly, I mean quickly go to 0. Think about this, you probably worked 10-12 years by now, and if you compute how much you made vs how much you saved, it's not really that much. If you made 50k a year, that's 500,000 in just 10 years and think about how much of that went to expenses, tax, etc and you barely saved just 10% of that. Look at people who won the lottery, they made millions yet they always go back to 0 unless they invest wisely. Let me say being stuck in a different country with 0 money and trying to come back to wherever you came from is going to be an impossible task. It's not about how little you spend each month, but rather how much you're making each month.
If you want to travel the world, I recommend a totally different approach. First I would look into investing into something. Perhaps a house or rental property that you can get a monthly money from. Try to make it to where you don't owe anything on the property by quickly paying down on any loans. Then all that money is yours and each month you have money coming in. The worst thing you have is where you need to do repairs, pay taxes, insurance, and any sort of in between problems. Assuming that, you probably only need 5k of additional money put into a different account to handle this.
Then you can go do whatever you want and have breathing room to go out and enjoy your time.
Not exactly a "workplace" related answer, but just some general life advice.
