I think the reason people dont get steady happiness or bliss is because they are always hoping for Grand things to happen to make them happy. A fancy car, high paying job, big house, true love, exciting party every night... which are hard to comeby, and for many people NEVER materialise...
Whereas if you look for happiness in small things, you would always be successful. Any car is better than no car... having A job is better than job. Small and cosy room is often more comforting than big palace... You might not be able to have a party everynight, but just a meal or a drink with a friend is brilliant!
If you can find happiness in small things (size does not matter

) you will find happiness easily. While waiting for Magical love, there's no harm in Materialistic short bouts of sex

Ok ok... Im sure you guys get what I am trying to say.

You might not have a garden, but even a single flower can make you extremely happy, if you want it to.
