The definition for good time varies from people to people. A very poor man will feel that time is good when he gets a square meal. A sick person feels that the time is good when he see improvement in health. A student who takes very great strain for studies will be happy when he gets a highest position. These shows that great strain is needed for getting good results.
People are happy to get good results with less strain.
That is against the law of nature. When planets move in their orbits and change from one zodiac sign to another, the change will be good for some and bad for some. Planets in bad position test the ability of a person. From this, it is to be understood that the test is a challenge. So when the time is bad, it is necessary to take it as a challenge and strain hard to get the results.
