Have you ever taught something to your customer only to have then forget everything they learned 2 hours later? How does this happen? Is it because they are ignorant and have a learning disability?
People aren’t ignorant; They just don’t care about the same stuff that you do, and so they don’t take the time to learn it. They are so busy and have so many things on their mind that they have prioritized everything in their life. There is not enough time in the day to learn everything, so we decide what is important to learn and what isn’t.
Therefore, your customers aren’t ignorant, they just don’t have the same priorities as you. You have made your business a priority and have learned everything about it. So, don’t get frustrated when your customers don’t want to learn what you think they need to. Isn’t that why they hired you anyway?
