Well, for myself when I worry... I can become more stressed and fretful and less able to perform in the present moment. I try to limit the amout of time and energy I spend on worry and for me, decided that it inhibits me from goals and wants/needs/desires I set for myself. I can choose to worry, but if I do, it is a self indulgence. I no longer have to stay there. It can be there "a worry", and I can still function in daily life, but if it becomes a paralizing thing... I am usually avoiding something. I also see my depressive aspects as self indulgence too. I can hold them now (the feelings) but they do not really affect me for days/weeks/months the way they used to. I no longer employ it to distract or procrastinate on things that need doing or my attention in my present.
"When dreaded outcomes are actually imminent we don't worry about them, we take action. Seeing lava from the local volcano make its way down the street toward our house does not cause worry it causes running. Also we don't usually choose imminent events as subjects for our worrying and thus emerges an ironic truth: Often the very fact that you are worrying about something means that it isn't likely to happen." ~ Gaven de Becker
"Basically, if the mind stays in the present, it’s impossible to worry. Upon careful consideration, it becomes clear that human beings are capable of worrying only about an event that has already transpired or one that may take place in the future (although the occurrence might have just happened or may be about to happen in the next instant). The present moment contains no time or space for worry." ~ H.E. Davey
"To live by worry is to live against reality" ~ E. Stanley Jones
"Worry is a misuse of the imagination." ~ Dan Zadra
