Story of getting an error :
We thought of an idea and starts to implement it on any language to make the idea work BUT according to the universal law, first code is all about errors.
We tend to solve all those but some errors remains there.
After trying for some time, we pause there and got busy in other stuffs.
After a day or two, when we are busy in something
Suddenly our mind stuck with the solution of that error and we proceed to build rest of the code.
If that error doesn't showed up, what would happen
> Time saved
> Code completed
BUT after in process of solving that error we goes through so many things that actually we learned so many things apart from that error.

SO THANKS TO THE ERROR FOR TEACHING SO MANY THINGS :)
