A wild thought! And fear of getting lost in the way.
"Days,months,years has past and I have been developing just about the same way I had started from the beginning of my career".
The above statement is not valid, its a lie, and can not be true, in fact its impossible. In my day to day job, I had to work with Microsoft technology to deliver clients needs. I my self probe round the web searching knowledge about my area.
Now the intricate part, each and every day lots of new technology is evolving. Microsoft is lunching many new technology. And I have to learn lot of stuff to keep my skills shinning. Well more importantly not only Microsoft, but the other technology vendors are also releasing lots of interesting technology which can work seemly with Microsoft product line. So those products are also in my learning backlog. Not to mention I am completely unaware of other technology vendors for instance like sun and Google.
Its really hard for me to keep up the pace with the improvements of the technology. I am doing daily work and finding some how i am left behind by the world. Choosing a particular field may save the day for a while but eventually no company require a specialist in "database" only. Companies require a developer who is equipped with all the necessary knowledge about tools that is necessary to finish a product.
"Learn Learn Learn"
So the tag line of developers is like the above three words. And it will not stop. So its not just "happy coding" its "happy learning" also.
