Adults are increasingly finding it difficult to live in the present moment.

Children are naturally living in the present, with no sense of time, so time seems to pass very slowly. But the more you grow up and enter society, the more brainwashed you become; the stronger your mind gets, and your mind is living within time.
You shift from living in the present and following your true heart to living with your mind, so it's natural that your sense of time feels faster.
In other words, your attention is never on the present. You're always thinking ahead in your mind, either reflecting on the past or planning for the future.
Either you're reviewing what has happened or contemplating how to prepare for what’s coming. If you're not in the present, you'll feel that time passes very quickly—one moment it's a day gone by, and the next, a year.
The mind is the cause of our sense of time. The more your sense of time accumulates, the faster time seems to pass, and the faster you age.
You can also return to the slow pace of childhood by learning to live in the present.
Explore the power of the present moment and its practice manual. Vipassana meditation is also recommended.
When your mind stops, you can break free from the sense of time.
Try this exercise: do nothing, close your eyes, and just watch your breath without interfering.
See how long you can hold it? Isn’t a minute like a year?
Try putting down your phone and doing nothing but sitting still.
How many minutes can you hold? At this moment, does time still feel fast?
If you quickly feel empty and bored, it means you're used to living in your mind, killing time with mindless thoughts, scrolling on your phone, playing games, chatting, or binge-watching shows.
You've killed time, so of course it feels fast.
Isn't that what you want? Because you can't stay in the present, you try every possible way to waste your life, then turn around and blame time for passing so quickly.
What you truly need and want is never in time, never in the past or future—it's always in the present.
Learn to bring yourself back.
Once you get used to it, you'll find true satisfaction.
