The competent individual has a firm sense of the capability they possess and capability beyond. Periods of doubt creep in, but that leaves room for growth and maturity. Periods of doubt are painful, as the individual moves from an ordered world to one where there is doubt.
In this chasm, most of the problems we face are self-inflicted. Looking at any problem we encounter, there are the following characteristics. The problem. The problem’s impact. The cause of the problem. The context. And, then, there is you.
You (and we, because I have the same problems as you) are part of the problem. You have made contribution to the problem and its impact. You may be the cause of the problem. If you don’t face your contribution, any solution will leave lingering conditions for the problem to resurface, perhaps uglier than before.
It is always easier to deal with an external problem out there, than an internal problem closer to your heart.
