I own a landscape construction business on the side. I have 3 guys working for me, 1 which handles my day to day business on site. I handle of all the estimates and the meet and greet of the customers. I usually schedule my estimates in the evening and sometimes I take days off when I have 4 or 5 to do during the same day. Thats when I get that 24hr flu but my business has been a very good success so far. If you do decide to start a business and you get to the point where you have people working for you remember this 1 main thing. Don't ever let your lead person know how to do everything. Using my business for example if my lead person knew how I did my bids or even what to bid for a job he could open his own business. I handle the ordering of all material, billing and payments are made only to me when the job is completed. I trust my people to a point but I use to do this kinda work before I started driving years ago so I know what goes through the mind of the laborer. Good labor will eventually think they can do better by going on their own and will do so. I have no problem with my lead guy if he ever did leave he's learning the skills he will need to perform in the business. Im not going to teach him how to profit from it also. Thats something he will have to learn when he goes on his own.
I've thought alot about these types of behaviours in the past few years.
As a drummer and rhythmist, i personally love teaching people everything included, the absolute guarded secrets to the utter basics. Only the ones who want to "get it" will get it and apply themselves and that is something I've learned growing up and older. This applies to almost everything in life. I could show a million people A through Z and only a handful will really make it to where they want to be, and those same people will be there no matter where they get it (slightly different avenues, for sure)
Bolded above, this is exactly the reason alot of work that gets done, if at all, is half ass. You draw the line somewhere, and the line is short of where it needs to be because you're insecure about teaching others a skill out of individual selfishness and because you feel as though you're too important and time is too limited to be bothered, plus you'll recieve more competition and be forced to work harder. That's not the way I will ever approch life, but to each his own I guess...
