Congrats man, you did the right thing by getting an office space. It costs more than starting from home but it legitimizes you and give you a professional environment. The number one thing that worked for me is keeping a positive attitude and knowing that there are going to be ups and downs. Invest invest invest back into your business in forms of marketing, hiring, educating yourself and your staff, and streamlining your processes. You are what you do daily, so if you put together some good processes and you are consistent with them you will succeed. Good luck!!!!
