This quote speaks to the subjective nature of time. Essentially, it means that our perception of time is not constant; it varies based on our actions, emotions, and experiences. When we are engaged in an activity we enjoy, time seems to fly by. Conversely, when we are bored or in a situation we don’t want to be in, time seems to drag. This is not a physical change in the passing of time, but a psychological one.

The second part of the quote implies that we have control over our perception of time. We can choose to engage in activities that we find fulfilling and meaningful, which can make time seem to pass quickly, or we can choose to focus on negative or monotonous aspects of life, which can make time seem to crawl.

Applying this idea in today’s world, it can mean that we should strive to fill our lives with meaningful and enjoyable activities, to make the most of our time. If we feel like time is dragging, it might be a sign that we need to change something in our lives.

In terms of personal development, this quote can inspire us to take control of our time and our lives. It encourages us to take responsibility for how we spend our time, and to make choices that lead to happiness and fulfillment. It also suggests that the way we perceive time can be a reflection of our mental state, and that by changing our activities or attitudes, we can change our perception of time.
