Happiness is a state of mind. Not necessarily it depends on how much money and wealth and luxuries you have.
After a sound sleep of night taking sip of a hot, cup of tea / coffee can be a best experience.
Looking at sunrise, the plants, buds and colorful followers in the morning can give utmost happiness.
A farmer sows the seeds in the farm on the ground, wait for rains to come and rest patiently and one day when he sees the crops and greenery all over his farm it brings smile on his face and also the happiness.
A student work hard, read a lot, forgo many things like playing with friends, watching TV, going out and relaxing but when he / she scores good marks and when it is appreciated by family, friends teachers and others then all the pains gets vanished and it gives happiness.
See the happiness in small things. All such small happiness in life collectively make us happy.
Dreaming about big things is good, but when you can't fulfill your dreams you get frustrated. Never look at what others have ... see how happy you are in what you have. That doesn't mean one should not dream for more. But give time and till such time you get what you wished for ... Don't be just after what you are seeking for but at the same time enjoy and find happiness in small things.
