Now or never ! Is it true?

It is often said, do it now or never otherwise you will lost this   opportunity. It is a serious case to study, because one opportunity can't decide your future because life is full of opportunities but this also not mean to ignore things and left it before completing. We often loose hope from any particular work we not get success immediately. It maybe because we don't have that ability to do it constantly. But the truth is that success never came instantly it is a slow process which is achieved through constant practice and thirst to do something . But not always we reach our destination though we do it with delligence but then also it's not a matter to worry at all because some times destiny also decides your future and may be you are perfect for what you got.
        The day you started thinking that you can't proceed  means you became older, never stop trying something new maybe you can achieve what you were waiting for.
