Parenting Teaches Allowance

If you're the kind of individual that has the pattern of being in relative control of your surroundings, then parenting is, in My Honest opinion, an experience that will help to release you from that burden. If not, then you will likely need a psychologist to 'set you to rights'. Honestly, you will have to let go, either willingly or painfully. There may be 'pain' of sorts in any case.
Kids are spontaneous, and do not follow a 'procedure'. That way of living that we teach them--code of ethics, ways to interact with others, basic living principles--comes by through example. Of course they learn these things in stages as they go, as we all do. Through this, you as a parent learn So Much about yourself: your tolerance, your patience, your flexibility, your weak points, your inadequacies....mostly the weak links in your own internal chain of operations.
Parenting is very revealing. You can't fake This. The learning--Your Learning is On. Big Time.

There is faith, hope and love, but the Greatest of these is Love.
