Life is never same, it is always changing and will always change too. What you have today may not stay with you tomorrow. What you wish today may be there with you tomorrow. We are born so small and grow up to be an adult in a fully grown up body, if the body in which we are living does not stay same, how can the circumstances around can stay same. We will have difficult phases like a child gets teeth, that time his gums hurt but later on these teeth are used to eat food, so when we have difficult phase, the strength which we acquire at that time is used to chew the problems of life. The funny thing is we dont have option in any of the case, you cannot stop the growth of teeth and you cannot stop the difficulties of life, they would come from every door and window and even if you close everything, they would suffocate you inside. So what is the option, may be we can accept that it is there instead of ignoring it and when we have to fight it, anyway we dont have option, may be we can fight with a smile, the smile which is the acceptance of life and the smile which will invigorate you with new zeal. It does not matter how big is the problem or the situation it has to get over one day as nothing stays permanent but if you accept the things with a smile, it shows how good you are at handling things because life is not about easy sailing always it is about difficult times too as those difficult times give us more strength and then we would know how strong we are.
