23 years young here. Just started in April after moving from Midwest to the Coast this Winter. Hoping to gain good amount of mowing clients and to do some small installs. And by April 2014 grossing 50k a year. Already enrolled in Hort school at local college for fall. I agree with Jcontracting that it's about the numbers of the business and staying on top of them. Keep numbers and spread sheets weekly if not minimum monthly so you go back 3 years from now and compare what you did and what doing currently. I believe in never stop learning and reading. For all you young guns out there take the time and read through this thread if you haven't. Even if takes you a year it's worth every page on it and priceless insight on the industry and how grow a successful company.
