What is the most important thing one should change for changing himself/ herself?

The answer is your imagination. What you imagine, you become ,
so if you want to change yourself, change your imagination .

I will tell you my friends story,  his name is ragav maheaswari , he is Pershuing b.tech with me in the same branch i.e mechanical engineering .

once he went to the nayi sadak for purchasing new book( delhities may know about nayi sadak), he spend 5-6 hours for purchasing book as the market of nayi sadak is so wast and big , so for identifying book and on barging he spend much time.

Personally saying , its a quite common action for a student who go there to purchase book and thats  not a big issue . The issue is what he did next.

He thinks that he is quite used to of that place and even then he has wasted his much precious hour in this, what about the first comer guy, he start thinking on that and consult this problem to his another friend and collectively they start spending time to find the solution .
After a long cudgel brain ,they think that purchasing a book is a difficulties and if it is a difficulty then we should provide a solution to it. They start a company who collect books direct from publisher and provide that book on normal rate to the students. Till now, their company grow exponentially and 7-8 people are working under their leadership.

What was the main thing which he do and other people don't?

The answer is he imagined.  He tried to imagine problem and find a solution and what other do? They purchase the book, do complains and rest all clear to them.

That's the power of imagination.

After listening his success story , I start making conversation with him on that issue, few points of our conversation:-

Ragav:-
Have you ever notice what is main  the difference between an achiever and  an unachiever.?

Me:- their hard work '( quite common answer')

Ragav:-
The real answer is their power of imagination and their  believe on themselves , while an achiever always think that he can do thing, ready to tackle difficulties and most importantly start believing in himself.

On the other hand unachiever always has excuses , not willing to break his comfort zone features and always has a fear.

Ragav:-
The next question arises what do they fear?

Me:- faillure

ragav:-
Correct,but not sufficient answer, They actually fear the unknown failure,what other will think , and they even fear success . as a result of this , many find themselves living as " lives of quiet desperation."

Me:- and???????

Ragav:-

And some great unachiever consciously allow past failure to determine their future. They unceasingly re-live their past attempts and failure. They think because it didn't work out then, it probably won't work out now.

Me:- so what's the last thing wanna to convey to me?

Ragav:- just dream because dream are formed in the imagination and power of imagination is unstoppable.

Don't go where the path may lead you, go where there is no path and leave a trail.

If you want more, then you must become more  and that's all....................
