First day of work and I WANNA QUIT ALREADY!

Basically, my job is to pitch around at hawker centres and foodcourts. I'll have to sell 20 sets of worthless pen which cost $9.90 each. This is tough man. Transportation fee is on your own. No doubt you can earn up to $1.6k a month but it is really tough.

Should I carry on or quit? My legs are aching already :(

My throat is bleeding :'(
