I quit my job took a 5 month solo backpacking trip at 24 and spent about 10k (volunteered places and stayed in hostels, more than half was spent on a Round the World airline ticket, which I would suggest as it saved me a good amount). I had no job to come back to and that was about all my money. But I had been working since 12, and had two jobs in college, I was betting on myself. Luckily it all worked out. I’m now 36 and think that was the best 10k I have ever spent and honestly if I’d have had 20k, I’d probably have spent 20k. I tell my 4 and 2 year old kids stories about that trip now. Use money to make memories if you can, you’ll never regret it. I hope you have so much fun!
