The capacity of any individual needs be determined for a specific task, before expectations are made, else disappointment may be i evitable and avoidable pain caused! Age is not a measure of maturity!
A child may excel in one subject and struggle badly in another. Persistent demand on the child to perform better in the apparently weak subject may result in increasing anxiety, with feelings of worthlessness!
Patience and appropriate support matter a lot, noting that every one develops at different paces! Corn kernels don’t all pop to fullness at once and the same heat that pops some may burn others!
Growth is not development! An adult body may house a child’s brain. Expectations beyond that mental capacity, will therefore be a set up for disppointment with risks of low self esteem, burn out or feelings of worthlessness, on the person subjected to undue pressure and risk of harm to others from frustration! Know your child and their respective capacity in various ways, know your clients, know your companions on life’s journey and resist the urge to place demands in excess of capacity.
