Today is the Yesterday of Tomorrow

I always asked myself this question
Why is that as I grow, I feel more depress and stress

Now I know
Because I compare
I compare the 1 moment in my past which is happy and relax
And feeling unsatisfied with what is happening today
And as time passed
this stratification of today accumulate
This result in misery in life

Today is the Yesterday of Tomorrow
How I feel about Today determine my Yesterday
How I feel Yesterday determine my Tomorrow

We can be unsatisfied with today
but maintain optimistic about tomorrow

With the right attitude
no matter what we do today
as long as we tried our best
and we know we tried our best
Today will be a good Yesterday
and Tomorrow will be optimistic
