Remember, being intelligent has different aspects to it.
Most people are mildly intelligent through their personal interests (background,culture and beliefs, practices, and habits) which they cater enough knowledge to work with.
Yet, sometimes vigorous training to almost a factory-robot like study regiments with correct information can conduct a greater sensibility than of someone who isn't learned giving you a advantage of being smarter than others who are not in the know.
Okay, in simple words you may be a bird brain but if you learn how to build a boat from a master shipsman than you'll fair off way more better than the person who never knew at all attempting to build his dream sailboat.
So I think smarts is rather an acquired skill than a ability handed at birth.
Because the person who is always studying is going to be stronger than the person who knows it all.
It's good to have decompression time to unwind and review oversights.
Don't let your self be overwhelmed with sensory overload which can lead to illness. Stay well and balanced!
Peace and Blessings! To All Of You!
