Time and the way it passes has always been an important topic for philosophers, religion and science. Whatever they may have discovered until now, what every mortal knows for sure is that time is irreversible and our most valuable resource.

As children, we don’t really have the notion of time, as it seems to pass in our favor. We cannot wait for the next day to meet our friends again for playtime; we want to grow up and be better adults than our parents ever were because we have it all figured out.

As youngsters, we already know what we want to become professionally, how our dream house looks like and we have a perfect family portrait painted in our minds.

As adults, we always feel like we need more time, but do we? Maybe if we’d learn to use time wisely, no matter how much we have at our disposal, it would be enough. Maybe if our decisions will not later transform into regrets, time would become our friend, rather than our enemy.

We cannot travel back in time to do or undo things, but from now on we can try our best to make tomorrow a happier day.

Here are 30 time quotes that will teach you its unparalleled value:
