The important trick in life is just be happy and don't put any conscious thought on it because once we become aware with it, we begin to “fear losing it”. Thus, we will put pressure on ourselves in an effort not to let it slip from our grasp. The surest way to misery is to be enslaved by fear. Fear of losing something we gained. Yet sometimes we have to lose it (painful as it seem) to make us more appreciative (especially of those little blessings we normally take for granted) of our everyday bliss.
Take the case of electricity, it's so much a part of our everyday existence that we take it too much for granted. Just imagine a brownout that last for 10 hours. What do you feel when electricity is restored? We used to complain when our internet processing is slow. But imagine 3 days (or a week) without internet? I guess we will be all smiles when service is resumed. What about water shortage? How many times have we complained about this or that, then when it took a leave of absence (electricity, internet, water), it was then we realized how much we missed it and how good things were for us. Some people just never learned because when they got it back they return to their old habitual indifferent approach (and the same misery awaits them again once they lose it). But for some, after getting that something back, they begin to see things in a different light.
So what's the message here? When you are feeling down and depressed that things aren't going the way you want them to be, just go out and look around you because blessings are really everywhere (plentiful and overflowing).
Some we see (material stuff and all), some we feel (love, attention, care, good health). Still some others are so much part of our life that we never even think of them. The mere fact that we wake up every morning is something to be thankful already. The mere fact that we can stand up and use all our faculties in our everyday activities is another reason to be happy. Heck, just close your eyes for 3 minutes and grope around until you become frustrated and lost, then open them again. You'll realize how good it feels to see again.
One of the best ways to be happy is to always remember and count our blessings.
