One common mistake is: having too much passion and refuse to pivot. This is somewhat a grey area. First, your idea might not be even new and there are many competitors or alternatives (which is more dangerous than direct competitor). Then you end up convincing yourself: yeah, I will be the next Dropbox. Their idea ain&#x27;t new. Second, even if it is a new idea, you tend to see many problems along the way in term of market adoption. You refuse to change &#x2F; pivot. You will fall into the circle of denials because you think your product is not up to the mark yet.
