7 years ago I got on an airplane. Haven't been back since. As for money? Get a job while abroad.
To those who get homesick on a trip here is my advice.
Suck it up!
If you give up halfway through a trip because you miss home, food, gf, etc you will regret it. You'll go home at the end anyway so that part can wait.
Food you can make. Look hard enough and you can find most ingredients. It's that key one that you won't find. You'll survive.
GF can come with you or visit. If she doesn't want to or won't wait for your trip to end then she's not worth it.
When friends and fam ask when I will go back I ask then when they will visit me. Guess what the answer is most of the time lol.
These days with internet, skype, mobile phones and cable tv there is no reason to miss home. Think what it was like back when you had to get on a sail ship and set off and possibly never come back. No way to communicate. It must have rocked!
And after all this time I have found out that home isn't where the heart is. It's where you feel comfortable going to the toilet.
I love traveling. Yes, I know I'm odd. Left my country 22 years ago. Still consider it my home but I wouldn't give up the traveling for anything. Plus the feeling you get when you fill up a passport is great.
がんばって Y'all!
A question popped into my head, how to take into account the need to return for NS reservist?
