I ran an online business unsuccessfully before. I need guidance so I can be successful this time.
It seems you need to develop a plan that will serve as a guide, a map and a system to keep you on track. Talk to people in your industry, network and ask questions. You�d be surprised at the amount of information people are willing to share. Use it to develop a framework you will follow with discipline and consistency.
Also, learn from the mistakes of your first business. Not every business is successful, but you can always use those lessons to make your next businesses work. Sometimes knowing what NOT to do is as important as knowing what you NEED to do.
All the best.
