Default Constancy of the Light Speed !

Hi Guys,

I'm a relativity hobbyist. I am getting intrigued by the postulate of
the special relativity which says that the speed of light is constant
in vacuum.

Further on, the theory of relativity also says that the speed of light
is independent of the reference frames. Now, as per this theory,
someone moving at at the same speed as the speed of light would still
find that the speed of the light beam moving parallel to him as 'c'
(which is a universal constant) !!

I feel that he should find that speed to be zero, as he himself is
moving at the same speed as the light beam.

I know this confusion should be due to my lack of proper understanding
and hence could anyone please shed more "light" on this ?

Thanks.
Astro.
