What is the meaning of living?

Some people pass away at 33, others at 44.
You must understand that we don't only die when we get old, but can die at any time, anywhere.
After a hundred years, time will erase all traces of you in this world.
The meaning of life is that your brief few decades of living are actually just for experiencing.
So, don't worry over trivial matters, and don't punish yourself for others' mistakes.
And most importantly, don't let unhappiness fill our brief lives; life is only a one-way trip, with no return.
