Impermanence Teachers

Whenever I find that my positions in life are on shaky ground, I turn to the idea of the 'impermanence teacher'; someone who is in my life to teach me about the nature of change and what I am most attached to. I think about this particularly in light of the idea that there is no job security in life anymore. Actually, I don't think there ever was as such, but one thing I can learn from it is not to rest on my laurels, and to always know that what feels secure one moment will change to something different later.
   There are two analogies I have lately adopted to understand this principle. The first is that of 'putting money in a savings account'. This has to do with the idea that keeping money just the way it is will not pay off in the future, and will only lead to a depreciation in value. While one has heard the expression "a penny saved a penny earned", in fact, today's earnings will not have the same value tomorrow. Even in the purely economic world, there is nothing whose value stays the same, and one has to keep renewing her or his vows to commit to things.
   The second analogy is more like a slogan or an expression I have learned recently, namely that not doing something is no longer an option. This seems to apply to companies in particular, as they start to face greater competition and need to keep looking for new strategies and solutions. In this case, there is no such thing as 'maintain the status quo', because what works well today is definitely not guaranteed to be just as successful tomorrow.
   Competition is not necessarily good or bad in life (it certainly depends on whether it is friendly or full of avarice and ego), but I wonder if perhaps reframing competition as 'impermanence teaching' might make it more meaningful. That is, by seeing competitors as people who teach us that change is constantly arising and one has to continue to innovate to keep up, could it be that they are teaching us a deep spiritual lesson that is rooted in the cosmos?
