This is an On the Go Side Job (I'll call it that way) because i have to work in their place. I usually take the Take Home Side Job, i find it more convenience because i can manage the time myself.
From my experience, not so many though, :D here are some tips for On the Go Side Job :
1. Use comfortable clothes
body fit t-shirt, and comfortable trousers + shoes,
so it's easy to move, cause it'll be tiring working until dawn :p
2. Bring this important stuff
coffee cans, fight the sleepiness
keep you focus and concentrate
ONLY if you're smoker, like me :p
Really, if you don't know the place, you better bring this.
It could be a battlefield there, you and the mosquitos
3. Make sure you know taxi's phone number
You may finish your work in the morning, tired and sleepy, and nobody can pick you up, who will you expect other than taxi? DONT take another public transportation. I once fell asleep on the way home and awake in the last stop.
4. Get proper eat and sleep
Forget the diet, and if you have spare time, sleep. Even though watch some DVD or read a novel sound like an interesting idea, don't do it. DVD and novel can wait. ;)
There! I'll share the other later (if i find another) after this project!
