The Opening and Closing of Doors

Life can easily begin to feel like one thing is getting in the way of another,
That needing to take care of something or someone prevents you from doing something else which may be really important to you.

Or it can seem like a never ending series of doors opening to you just when and where you need them to open. You will be able to see this if you are not overly focused upon any door which may be closed or closes as you approach. Both the opening and closing are part of life, it is much like seasons and tides. Rising and falling, opening and closing are necessary parts of  larger, longer cycles. One can not really continue or come into being again if what seems like its opposite does not also have center stage for a time. Dealing with both is part of our learning.

If you focus primarily upon what you are unable to do (because of something or someone ) you are likely to become negative and resentful.

On the other hand, if you are able to take those inevitable closed doors in stride, move on and keep looking ahead rather than back, then you are far more likely to notice the many other opportunities which continue to come your way, if your own doors to the outside world are open rather than shut.

How individuals see things is often described in terms of being half full or half empty. It's our self assessment as to whether we are positive or negative. What's operating inside of each of us is a response system.
As a species we are set up to notice targets of opportunity. It is a survival mechanism. If we lived in the wild, we'd still be keenly aware of all potential food sources or places of possible shelter, but in the absence of such pressure, we sometimes slip into states of feeling sorry for ourselves. We are capable of seeing a closed door as a personal disappointment, a great defeat which can derail our personal progress. How we perceive any given door whether open or closed has a great deal to do our prospects for the future. If we tend to dwell upon doors which are closed we may assume that an open one will soon close and that there's no point in even moving in that direction. But if we are open, if we are actively looking for open doors, for opportunities, then we will see so many possibilities, perhaps more than we will ever be able to follow up on. But that is a problem of overabundance, which in not a bad kind of problem to have.
