Cognac, If you are a great mom and are great at business, my hat is off to you. These qualities may not be the total "package" of what you are looking for, however, they are the basic building blocks of "outside" worldly success. Many worldly people could have fallen into the successful group without having both of these qualities at the same time.
I personally feel that the indoctrination of WTBTS of constantly insisting that "I" personally (along with every other reader) was grossly deficient, prone to failure, tempted and sinful, and totally inadequate without the WTBTS's input and dependence on their constant guidance, distorts a truthful judgement of ourselves. This type of "spiritual diet or food" is intentionally done to psychologically keep followers off balance and doubting themselves so that they feel dependency on the WTBTS. It is very similar to a drug dealer.
You have not reavealed enough of why you feel inadequate "to make it in the outside world", so I won't offer correct actions, but I'm interested in your further expressions.
