The survival of the fittest applies even to modern-day society.

You are as good as your last day.

Your good days are now long gone and it seems that you are stuck on bad days.

People forget easy because you know,

as they say, these things come and go.

Someone better will replace you because that's what people want.

Something better.

Something better to keep on living the life that they want, but you know

what they said to you was true as long as they wanted to last.

It's just that one day you are not fit for them and eventually you are replaced by someone who is now fit.

From fit to weak...

There's your appreciation and how unique you are.
