To a lot of the newbie in twitter it may seem as a silly site where no one sees what you write except for the bunch of the followers you have. But the truth is entirely different and one thing that you would realize is once you have something interesting posted out there it will surely reach out the audience it deserves no matter if you have 10 followers of millions.
Twitter is a place where any interesting thing attains the exponential reach.. you can compare it to a forest fire which might have been initiated just by a single spark but it becomes that fire which cannot be doused..
The key here is to be an optimist (bye the way my twitter handle is @0ptimyst). Believe in you and you would attain what you are destined to..
