Have you ever thought about why the intelligent ones can sometimes be so full of doubt ?
I will take it to be the result of having gleaned and gleaned; seen and seen; studied and studied and being led so much into how one does not know and how much there will always

be to know when they know.
They must have been exposed to tons of reason why and how things in life could go all wrong to such an extent that they don't really give much room to tell themselves in that shoe they've known so much too.
And it's really no surprising to me that

most times they find it hard to go easy on themselves and they just like every average human being would need to be intentional about self-management, building a confident stance in life, fine tuning their commutation skills and so on.
Doubt, overthinking might just be the

greatest inhibition of the easily and extremely knowledgeable ones...
Indeed letter kills.
