Time is an interesting concept. Despite being objective in its nature, it's highly subjective in our perception and lived experience. Time can move fast or slow.
Not every hour in our day is created equal. The quality of the time we spend highly correlates with the energy we have, our mental and physical state, the surroundings we are in, and other factors. You can spend a high-quality hour filled with excitement, good work, and well-being, or a low-quality hour with stress, distraction, and dissatisfaction. The way you design every hour of your life is your choice.
I like to think of the quality of my life as the sum of the hours I spend in a day. This allows me to check in with myself honestly and remove intellectual reasoning on how happy or not I am in life. When I notice that there are too many low-quality hours in a day, I reflect on it and try to come up with something I want to change to fix this.
Framing your life through the lens of the quality of time you spend every day is helpful in making unconscious patterns visible and gives you the chance to change them. We all have the same 24 hours, but we don't spend our hours at the same quality levels. If you feel unsatisfied with your life, this is the first place to look.
