I also think if your talking about what people don't factor in. Before you ever start a business, ask yourself, if you have the stamina health, attitude, and funds to support you for a year at least.
You know there are "growing pains" things that happen beyond your control, you have to be able to solve problems as soon as they come up. You cant have a defeatist personality.
There is no time to wine about whats happened just accept it and get around it, or make it better.
Is your family able to help where you used to do things? I know we personally devote about 16 hrs a day to our business right now.
I NEVER could have done that when my children were little. But look at any successful person, nobody gets there working 2 hrs a day. Theres no magic pill.
I just cant wait for the day in a year or so when I can get away with working an 8 hr day and everything else run pretty smoothly.
Like the Dropshipping wharehouses in this software, that alone will save me 4hrs of work a day once I have it set up and were getting the orders Im expecting in a year.
