yeah, doing service is always a beautiful thing doesn't matter the size of that service, the value is on what you like to do and how to put it on service, I like to play at my city, on Caracas, specifically on the subway where most than the half of the city tends to use daily and I like play music there, is kinda a social service cause minimum salary here is near 4$ a month so, what people gives me on subway as tips works for me to pay my subway tickets and bus tickets, cheers!
