I would like to thanks indiaunited for giving us such a though provoking topic.
As much as interactions I do under this topic I saw people writing that others think "success meant to be wealthy" and then they express their opinion and give definition of Success by using their own thinking but I think so every person who ever think... I mean overthink...
Always had a specific and new definition of success.
For me success is all about "what makes you happy" whether it's profession, wealth, family, relations. Like some people say that they are successful and they won their life because they own good friends who always support them in their ups and downs, other will say I'm successful and I won because I achieve whatever I want to achieve (goals), somebody else will say I'm successful because my family is not unlike those family members who betrayed each other just for money or property. So success definition vary from person to person or you can say "life experience to experiences which make them what they are now in their life".
Tomorrow, I was watching sky where clouds were spreaded all over white and sky color were making sky look wonderful I can't explain beauty of sky I don't want to divert my eyes from sky. As soon as it start getting darker and darker I notice that I should capture this valuable sky because it wasn't looking ordinary but when I do capture it in my cell phone I realize that I lose the actual beauty and now due to darkness could are hide under the dark color of sky which makes me sad but on the same time I saw a small "heart" made of cloud makes me happy again. What was that? Sudden fluctuations of mood? Naaaahhh it's what makes me happy and sad if I was able to capture sky on that time I will absolutely share it to those whom I love. My family members, colleagues etc. That's my success that I capture the picture that I want to capture on that moment but I prove that success isn't directly belong to happiness you can find your peace of mind alternatively when you didn't got what you goal for.
So in short for me what makes you happy is the small, accurate and precise definition of success. It might be what you achieve, what you own, what makes you sad and happy and what fluctuate your emotions.
