The world is full of surprises

We often hear people say that the grass is greener on the other side. That means, People tend to believe that someone else's life is better than themselves and that they are happier and more prosper than them.
But the reality is one should only focus on his own life and how he can make it happier rather than wondering about someone else's. One should emphasise knowing what he want, what makes him happy, setting goals, embracing the present, and taking massive actions. Create such an environment that no time is left to spend on these meaningless worries.
Surround yourself with people, books, activities that positively uplift you. Focus only on your lawn, water it regularly and someday it will be greener than any.
