Idea A is successful.
I think Idea A is a bad idea
I think my idea (we shall call it Idea B) is a much better idea than Idea A
Therefore Idea B will be successful.
While to some this might seem like simple logic in reality it doesn’t work that way at all. First of all, we are rarely objective about our own ideas. Secondly, just because we think something is a good idea doesn’t mean others will. Thirdly, even if others agree it’s a good idea (or even better), it still doesn’t mean it will be successful. There are so many other factors that would need to be taken into consideration (timing, sales, marketing, other ideas, reputation etc).
Remember, just because you think you have a better idea doesn’t mean it will be more successful…but it might!
Have a great day!
