“It is essential for you to remember that the attention you give to any action should be in due proportion to its worth, for then you won’t tire and give up, if you aren’t busying yourself with lesser things beyond what should be allowed.” Marcus Aurelius, Meditations.
There are some things in life that we don’t like doing, but that simply need to be done. How much emotional energy do we invest in them – moaning or complaining about the unpleasantness of the task, when we’d rather be doing something more rewarding?
Try to see the positives in what you are doing, and use the thought of achieving that end to motivate you. Alternatively, how bad would it be in the longer term if you did not carry out this oh-so-onerous task? Don’t sweat the small stuff; it is what it is. Onwards and upwards. This too shall pass.
