Unknowns....
There are many things we want to change but can we? Can we return to who we once were? Can we make ourselves a better person? Can we change the life of our friends? Make their life better?

Personally, I firmly that we can do all those mention above except to return to who we once were. But as in how to? These are left unknown, unknown to us, pure human. It's not just a mathmatical problem where you can solve it eventually.... Or even know the steps to solve it... It's the challenges that we faces... Perhaps we'll figure it out along the way or even, we dont know even after we part this world...

We lived on the same tree, same universe but not necessary in the same seasons.

Leaves changes according to seasons but since we are not in the same seasons, we change at different stages of our lives..... It's a never-ending cycle... Some at a very young age, some later, some never change... However, sometimes, we dont even know what season we are in, how can we help others to change to another season?? Perhaps, we can only influence, guide, not by helping them directly....
