There are lots of preconceived notions about growing up, being an adult, and the responsibilities associated. The truth is you often don’t grow up if you don’t or can’t take up the responsibilities. They come first, not the growth because they drive the growth.
Sometimes we wait around for time to pass so that we have “grown up” and can take on some new responsibilities. But the age doesn’t mean anything if you’ve just been wasting that time on nothing but hitting the number. So are systems that prize seniority in age or experience in years. Time is a proxy, not a measure of growth.
So instead of giving up because “time passes too slowly”, what are you spending your time on right now that prepares you for the responsibilities you want to take up?
