The journey of life,that which leads to greatness takes diverse routes.
Today it is one thing and tomorrow it is another.
Most times people live on past glories and the unfortunate thing is that they allow it blind them from seeing and working for the future nor dealing rightly with the present.
Yesterday is gone,today is and tomorrow is yet to come still man has to prepare for it.
The past,the present,the future all are but different with different occurrences and happening that happened and could be traced and link to a particular time period.
A man stays and everyday of his life,he fails to work,never prepares and doesn't even care about what tomorrow will be,what the future hold.
Ask him anything,tell him anything and the response will always of course be link to the past,the history and all that memories could bring.
About now? He knows nothing,do nothing because he's been blinded by the glories of the past.
There's another who may have or may have not got the glories in time past but Care less because he believe in the present, he accept that time and season changes because for him the believe that the true test of faitj lies in accepting that which is unseen is quite true or rather perhaps the hope to grow more,to gained more glories has been all he yearns for.
To this man the insatiable nature of man is another reason he simply cannot depend on past glories.
I am is different from I was, and again different from I will be.
You were,no doubt but what are you?
That better be answered from within. Or perhaps were will you be?
Again, that's rhetoric.
Depending on past glories often leads on to live in limits as one thinks nothing of the present and the future,hence,such person simply cannot grow.
You ate yesterday,ain't you eating again today?
Won't you eat tomorrow?
These are the very many reasons to keep doing the best consistently without stopping and looking back.
