Do you know how captive elephants are trained to not run away? They have these 15-20 kilo heavy chains around their legs. Now you would wonder why an elephant which weighs tonnes could possibly feel constrained by a chain weighing a few kilos?
Of course there is a backstory.
When the elephants are small, the trainers tie these chains around their legs/or to a peg. When the baby elephant tries to run away the chain pulls it back. It even cuts the baby elephants legs sometimes further causing hurt. Soon enough the baby elephant gets conditioned that it can’t escape as long as the chain exists.
This baby elephant can grow upto a multi tonne giant as an adult but in its mind the 15kg chain is a barrier it can’t overcome.
Many days of the year I am that elephant resigned to the memories of failure. Except I know the chains can be broken but am too consumed by my memories of feeling inadequate.
