this is my first year going solo. figured out i could make more money this way with the amount of customers i have. anyway, it seems if i work 6 hours and under, i'm good to go all day. but if i exceed 6 hours my dph dip because i get tired and cant work as fast. my question is, does this go away when i get used to working by myself or is this something i should just expect? thanks for replies. randy.
