Believe it or not, happiness is in our hands, well, with a probability of 90%. There are certain external factors which could, not prevent, affect that from happening. But still the majority of it lies in our hearts, minds and thoughts.
Happiness is a state of mind, aided by you-get-to-do-what-you-want-to-do, of course!
As for me, there are very small things, or should I call them subtle, which provide me utter satisfaction in life. And for the most part of life, if we are satisfied, we are generally happy - that's a golden rule I tend to follow. For me general happiness lies in my living area/conditions. The township I reside in is one of the greenest places of the city. And no one can argue over the fact that experiencing greenery around your apartments gives a serene, peaceful feeling within ourselves.
Second thing to happiness is - de-stressing, which can in be many ways, like sports activities, evening stroll in parks meeting with friends and acquaintances. And all of it again conveys that the locality we live in should possess these amenities and help towards a happier society in general. A few of my ways of de-stressing include playing Badminton in the indoor wooden court, having chai-pe-charcha & a sit-together at shopping complex, all within our township. On weekends, there's either long distance cycling, or running at a sponsored event. All these activities, coupled with a few more depending on the time and situation, really help in busting the accumulated stress out of mind. (Mind gets stressed due to various factors pertaining to modern lifestyle and work routine)
Thirdly, there are some leisure activities like gobbling or easing through a novel; reading, listening or writing poetry which soothes the inner self and brings calm to the outer self in process. Savouring your favourite piece of music, movie or food also comes under this category. All these things eat up surface tension and make us happy without us even noticing it.
Last but not the least, a mind or a body deprived of proper sleep is bound to be irritated. Such a personality can never squeeze the happiness out of anything. In other words, it won't be able to properly process any cause of happiness to its 100% extent. And a well-maintained home (with proper sunshine and air circulation in the house taken care of) in a seemingly quiet surrounding / neighbourhood is quite more likely to aid in better sleep at night hours.
Celebrate Life being Happy!
