We should not be bogged down by the bad times or adversities as they are the part and parcel of the human life and as they are unpredictable it is not a wise thing for worrying over those which are yet to be encountered.
As a living entity given a choice we will like to have an enjoyable life with no hassles but is it in our hands? Destiny has its own course. We have to just drive on that path not knowing who is guiding us.
Knowledge is power.
If we really wish we can feel very happy from even the most routine things and events. We have to observe children to see how they feel happy in even small and very cheap cost things. They may not even touch a very costly toy , but will find thrill and happiness on toys made of green leaves or those made using some waste items lying around. They would be happy and satisfied with the tiny 'jeera candy' than a costly chocolate bar.
It is about what we have in mind about happiness. There can happen some testing times in our life. But if we strongly believe that this is just a test or trial by God and once we pass this it would be far better and happy time. If one does not get overjoyed in good times, he will not feel over sad also in not so advantageous times.
We just need not lose hope when we are undergoing sad phase. Understand that it is the time to undergo struggle, once this phase is over, the happy phase will also be back because time changes as nothing are constant in this world.
So, just keep making efforts from your end, and you will be back to the happy and delighted moment soon.
Do what inspires you !!
In spite of all odds in life, hope is the best medicine which would cure all the reasons for sadness.
