Life today is a form of competition; a meritocracy that exists on many levels, from your career, to the possibility of being remembered by the world, to your dating life (if you choose to date).
In order to stay as much as possible on the top on these various degrees of life’s meritocracy, you have to give people a reason to remember and value you as a person and as a functioning unit in the world’s productive machine. You have to give your employer a reason to keep you on the job and not replace you, give your audience a reason to keep remembering you, and to give your current date a reason to not search for a better partner.
Gone are the days where people where worthier than others by their ancestry. The fact that your parents or grandparents did this and that does not, at least most of the times, give you a reason to stay ahead in life’s many competitive areas.
As an analogy, life can be compared to a car. If you will not maintain its condition every now and then, it will function less and other cars will stay ahead of you because they were more well-maintained than yours.
Life is therefore an arena; a battlefield of merit and competence where only the most desired and inspiring people gain all or at least most of the rewards life has to offer to you, given that these rewards are limited by both quality and quantity.
And remember the following: it is okay to lose sometimes, simply because there are better candidates at the current point of time. If someone’s CV is greater than yours, and you cannot improve your CV at the specific space of time where their CV has been reviewed, you just have to admit that they can have the chance of replacing you at your current job. It’s merely an example, of course.
Thus, if you want to do this whole “life” thing, you have to try your best at keeping ahead of the competition as much as you realistically can at whatever area in life where the benefits are not accessible to everyone. Remember that many things in life cannot be gained by all people, as they are limited, and thus you have to fight for their attainment, and even though there’s no weaponry to use, there is your merit, your achievements and your overall behavior within your arsenal, to be used for your advantage in the many races of life.
