18. You Asking Too Many People for Advice

It is always beneficial to get input from experts, especially experienced entrepreneurs. But getting too many people's opinions can delay your decision and your company might never get out of the starting line.

17. You Don’t Have a Written Plan

A start-up that needs considerable capital to grow and more than a year to turn a profit should plan how much time and money it's going to take to reach there. You must spend time thinking through the key areas that make your business tick and building a model for three years of sales, profits and cash-flow projections. You should put some of your creative genius to prepare a business plan. By doing this you actually understand how to transform your idea into a business. Set both short- and long-term goals for the business, so you can check your progress along the way. Without a clear vision of where your company is heading, your great idea can get muddled along the way.
