The plan for this summer vacation

I have a plan for this summer vacation to go out and make a living alone. It will be crazy for a freshman in China, but as the saying goes, "Don't crazy we are old" (Chinese famous literal translation)*. I hope that I can have a unique experience. It's the wealth of my life**.
I plan to go with 300CNY，some clothes, and a cell phone. The money will help me through the start of these days and emergencies. I won't ask for anyone's help during this time. I plan to work for a restaurant, distribute leaflets, or do others things to earn money. I know that I may sleep in the park, but that's alright. I guess I can stick to it for a few weeks (I should come back home before school starts).
That's all. Wish me luck! O(∩_∩)O

* I'm not sure what the translation is supposed to mean, so I left it alone (since you stated it was a literal translation). Maybe does it mean, "If we don't do something crazy, we are old?"

** Not sure if you are trying to say "It's the wealth of my life" or "It will be the wealth of my life," so I kept the correction as close to your wording as possible.

Good job on your composition and I wish you the best of luck with your summer plans! ^^
