Some Queries about my career

I am a 23 year old engineer now completing more than a year in Infrastructure Support Industry.I have cleared ny CCNA and regarding my next one I am in a sort of confusion..

I always wanted to learn linux right since my college days and now teh craving is even more.And when it comes to Linux RHCe seems to be teh most challenging.But teh questain that beckons me is “Is RHCE worth the effort,when it comes to my career ?”.Aftera;; at the end of teh day we are all professionals and we have to have some concern about our careers in addition to your interests.

Ultimately my aim is to enter into “security”.Could somebody help me with some authoritative advice..

Thanks in advance
