Thanks guys for your valuable inputs.
I am going for MTA certification (Microsoft) to brush up fundamentals before choosing a specific field that I assume would be either in Networking, Cloud computing or Security.
I assume it will be tough to start afresh after but some one said "The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, delearn, and relearn."
So I m off to a new journey.........
