We would not care whatever bad words someone said to us, how depressed we were after the break up, nor the bad grades we got at school.
The time would be too precious to be dwelling over something with no value in our lives. Instead, we would only focus on what we wish to do for the next 6 months.
If there is one truth in life, it would be the fact that we all die.
There is no exception. Royal families, young, rich, poor...we eventually all die.
So what do you wish to accomplish during the finite amount of time you have?
The past does not matter.
What matters is how do you want to be remembered as?
