Everything around us is a clear illustration of the above saying. Our mother earth passed through millions of years of evolution so that it could be inhabited by us. The world we live in was not like this since Adam. The comforts and facilities that we enjoy are a result of centuries of research and experimentation. First a seed is sown, then the plant watered, and only then do we see a flower blooming, or a fruit ripening. Same principle applies to human life. A child is born helpless and dependent on its mother for the smallest of needs, it passes through different phases of growth, observes its surroundings, learns from its experiences, and becomes a fully mature and responsible member of society. Every phenomenon in this universe is a result of gradual growth and development. It is therefore advised that one stays while working for the achievement of one’s aims.

Looking forward to comments!!!
Also please let me know about the length of a paragraph,is it really have to 250-300 words long or it could be smaller than that?

I think we are supposed to write 250-300 words in idea expansion so one should follow it.

Overall, your idea is great in above expansion if elaborated more.
Here is my expansion as well on the same title, plz comment.

Rome was not Built in a day

Flowers do not blossom in a wink of eye, seasons do not change by and by, child does not grow into adult within seconds, each of them needs time and patience.
All the luxuries like mobile phones, internet, helicopters, and capsule elevators that we are using today are the outcome of hard work of nearly two centuries. Man reached at moon after long experimentation and scientific discoveries. Knowledge of science and philosophy that we use today to enlighten our minds and hearts was inherited from Greeks and Romans around 2500 years back. Today we cherish the knowledge and literacy of Westerners; they had started work for today in 12th century with the establishment of first university. Engineers, doctors, and scientists, they all gain respect after years of hard work.
Similarly, Struggle for Pakistan was comprised over more than 150 years. Though the Quaid said that Pakistan came into being when first Muslim stepped at the soil of India. Struggle started with the War of independence 1857 and continued until 1947. Several lives were laid down by Muslims for the achievement of a separate homeland. Likewise, if we want to be something, we have to set the goal right at the moment and need to struggle for its achievement. Nothing can be achieved in a short while.
Everything to be in its fullest form requires time to accomplish. Those who never give up and believe in the worth of time eventually bears the fruit.
