Sometimes in business or any areas of life, there is something called compounding effect, you see all the results you are seeing on their page now is not as a result of them suddenly going viral and i believe it is not their first post.
What i mean by compounding effect is the results you are currently admiring on their page now must have being from the results of sleepless nights, un-bargained consistency, hard work, quality of work overtime.
Now when they were doing all these, they must must have sometimes got tired or even wanted to give-up at some point but they didn't, they kept going.
So, if you want same results, PUT IN THE WORK!
