Self-reflection.

I've come to Australia for studying English and Working.
That's why I got a Working holiday visa. Strangely, I feel like an odd feeling these days such as "Why did I come here? What am I doing in Australia?"
I couldn't find suitable reason.
I thought I could earn heaps of money and friends in Australia.
That was just a dream. This is reality not a dream. I had to realize it.
To be honest, that was not easy to get something which what I want even if
one small thing, for example, make friends Aussie(Australian).
People say that it's not that so difficult to make friends with foreigners.
Yes,,I think it depends on the situation what you are doing, your passion,
your endeavor, your challenge, your courage and time.
Sometimes I am curious how some people can make friends easily who are from foreigners.
Please let me know if there is a good way to approach to foreigner.
Maybe, if I change my mind and saying or speaking English to Aussie without
hesitation, am I able to make friends more easier than before?
