The meaning of Life should not be about a destination but the journey, because the moment you stop running is the moment you have arrived, the moment you will end.
Life is short, you may be in your 20s or 30s and it seems like you have so much time ahead of you but take a moment to think about it. How many years of quality life do you have left before you reach an age where you no longer can freely run under the sky and let the sun shine on your skin?
Maybe another 30 - 40 years tops, think about it, 30 summers to go, does not sound much now does it?
And one third of the time you will be sleeping, another quarter spend with work. Time is precious, don't waste it lightly, enjoy every moment, both the ups and downs.
Having ambitions is good, one should have a drive and goals but don't get too abscessed reaching for the stars, don't look forward for happiness, enjoy the now, don't merely exist, live.
You should never feel bored,
