It's not everyday that we have the whole time in our life. There are days especially when you're an adult, 24 hours is not that enough.
Why? Because we needed time to work, to gain something, to prove something... yet our time is still not enough. We always run out of time.
Bonding with our family and even our friends is also important, yet we just neglect it and focus on the very important things which we thought are important.
