Ignorance of certain things is a blessing because you are just covering yourself from getting some problems that you might not get if you are ignorant of them. For example, the people out there that don't know about social media and stuff like it, don't need to look for money to spend on their internet provider rather they can spend that money on something more beneficial. Other stuff like how is the celebrity behave even though they are not doing any praiseworthy things, people always followed their footsteps but an ignorant person still has the values thought at school which make him blessed from the other crazy people who are dancing in the middle of the road because of so-called trend.
