What's the worst mistake you have made in business?

Question

What should you have done to prevent it?

Answer 1

I went into a business selling a product that was of great interest to me but had little interest to my prospective customers. I didn't really consider the customer's needs as silly as that seems. I should have surveyed my potential customers to find out what their needs were.  

Answer 2

I waited so long to start my own.

Answer 3

i had a load of papers that i have been working on for a whole year and it was for my presentation of a new company and what they will do and a new chocolate that will be made there and i woke up late to go and then i got ther just in time and i went up and guess what i had left my files and documents at home and i had traveled 156 miles to get there.

to revent it i should have gone to sleep earlyer and set my alarm clock earler to get up and make sure i have got every thing
