What is enough? How do I “know” it?

Enough is an arbitrary mark. Set with either randomness or aspiration, the delineation, once made, tends to be static. Against this mark, I measure and gauge a position relative to it. I can, therefore, assess my having made the mark. The how is in the measuring. Left to whatever devices I use I may have relatively little competence in using, this measuring can, and does, prove faulty. Example: to see if I have enough gas to get from home to my mom’s, I use a device in my car which tells me how far the gas will take me in miles, and how many miles to my mom’s, the rest is math. Contrasting that to my sitting at a restaurant and deciding what to order and determining that I can afford something based on my ‘recollection’ of how much money I have on the card I intend to use. That sometimes doesn’t work out as well. Hunches are problematic in this area. Lastly I can cheat (and have) by moving the mark, remembering it is arbitrary. Example: realizing that a change in circumstances beyond my control I have reduced income and can no longer afford the lifestyle I am living. Rather than find more income, I can cut expenses so that when completed my lifestyle is within the mark set by the new lower income. I have done that many times. The why is also interesting (and not asked in the question). Sometimes it is a game, truly, a way to move through my day or a task. Setting a distance to row is one common example. Yet there is another reason. It is to be free of doubt, released from anxiety. Measuring in such a way that it discerns and sets, restores balance. Balance is essential. To me anyways. It allows me to walk.
