There are lots of business books and fields of study that provide advise on starting a new business. They do however seem to be a bit theoretical or vastly outdated. With this I am interested in hearing from you in practical and simple form...
I would like to know: "What was the thing that you forgot to take into consideration that had the biggest effect on your startup? Along with this how would you incorporate it in your planning for the next startup?"
Thanks for your answer, every piece of info helps build a more detailed and richer "puzzle".
