I know a guy. Young and sportive. I usually travel with him and another friend my same age 24.
All of us were talking about things and suddenly I got to know that this guy was married... a shocker and that he has an eight year old kid ... double shocker !
Not because he was married but because he looked so young. I agree we have film stars who look young enough for their age like Salman Khan who is now nearing 50. But this guy is not a person who follows a fitness regime, hours in gym or eats low fat food with green tea. I was curious to know his secret. There was none.
 
    However on taking with him I had a glimpse into his mindset/attitude. He was person who had an aim of having fun. He used to simply leave home during his younger days to places like Goa with friends.
Not that he is not responsible but that he doesn't let strings to be attached to him.
 Long story short he has clear goals- very few and not ambitious as per standards of an educated urban person but clear.
I know of people with a similar worry-free attitude with lot of passion and love for things they like to do who look astonishingly younger than their age.



LESSON: Have an attitude to have fun in every endeavour that one undertakes. Have ambitions that clearly lead to holistic joy in the end. Take interest in the world around you.
If being extrovert & having gigantic goals like most people around you is not your nature so be it. Just keep moving forward... always keeping a cheerful mindset.
