Ultimately, customers are your only source of funding. Tim Mullen

One would have pondered on which is the best to have. Frankly speaking, they are both important. The height of importance depends on the one that is nurtured most. Do I sound confusing? Don’t be in a state of five and six.

There were two unemployed men who went in serve of job. They both did study the same course but different school.
When they were interviewed, one was employed. Despite the fact that the employer needed two people for the position.

What went wrong between the two? I later found out that what went wrong was that, one was with mastery mindset, the other, marketing mindset.

This leads us to what the two words mean. And, how they differ.
Let’s take a look at the two.
