When you are your own boss you can set your own rules; And this is the beauty of my job! I am a certified heating and A/C specialist who works for myself. I am also known in some areas as an independent heating and A/C business, and one of my major rules is to always be done toil for the day by 6pm and to never toil overtime. It is not like I am going to make any extra money by laboring overtime like you would get on a hired job for some business, however when you toil for yourself, you do not get those perks. Sure, I could charge more to compensate, however that would just drive clients away. So I never toil after hours and I cap myself at no more than 40 toil hours a week. If there are any heat and A/C repair jobs that come in to be busy beyond that in a week, I will have to tell them that I can not help them until the following week, and if it is an emergency Heating, Ventilation and A/C situation to please call an emergency heating and cooling business to help them! Yes, that takes away some business, however it keeps me sane and at balance with toil and life at the same time; This is called smart laboring. Something a lot of people in this country have forgot how to do. I will not drive myself to an early grave like several do by overlaboring myself. I also suppose and stay younger this way. The message here is never overwork yourself.
