How to work in this competitive world according to teachings of Swami Vivekananda?

Question: Actually, one question is haunting me since so many days but I have not been able to get a clear solution. It is, I am very much inspired by the ideas of Swamiji, Thakur and Sri Sri Maa, and I want to mould my life according to their teachings. I was formally initiated by The Present President, Swami Ranganathanadaji Maharaj four years back and since then I am trying to practise the austerities sincerely. I am 26 years old , single, and working in a global software consultancy firm. My question is it good to give importance to one’s career or should one be careeristic? I take interest in my job but I am not at all interested to give all my efforts, time and energy to my career. But then, in such a competitive environment one has to strive to be the best otherwise one will just not survive. But also I am fully convinced that the worldy persuits are vague and temporary. And by going through the teachings of Thakur, Maa and Swamiji I am convinced of the goal of our life. so, should one take renunciation in order to achive the actual goal of our life? OR can one remain in the mainstream, do secular work and still practice the teachings of the great Masters? IN A NUTSHELL, how should I mould my lfe according to the teachings of Swamiji and thus channelize all my thoughts and activities to become A TRUE MAN ? I hope I have made myself clear.
For your information, I am in touch with the center at Mumbai, but I felt that I can discuss my question openly through this platform.

Answer: Most of the people mistake the concept of the Karma Yoga. Of course, even Arjuna was confused. Krishna has clarified it beautifully in the 2nd & 3rd Chapters of Bhagavad Gita. I wish you read it. Specially the book written by Swami Ranganathanandaji Maharaj. Now, whether one is spiritual or materialistic, he has to put his whole mind to the work. This is called as dexterity in work by Lord Krishna. Suppose, you just imagine, that you are directing an aeroplane which is flying in the sky by sitting in the air station below, through your computer. At that time, if the thought enters in your mind that this world is temporary, I need not put my whole concentration to it & you guide in a negligent way. What will be the fate of the people? You have to work hard & with full concentration, but, at the same time you should be detached in mind. It is a very high stage & an ideal stage.
The best way to mould your life is – perform your duty in the best possible manner and at the same time spend enough time to spiritual practices also. It also requires a good moral & ethical life. Read Swamiji’s (Swami Vivekananda’s) works as much as possible & I am sure it will help you to mould your life in the best manner
