Need some guidance for how to be a CCIE

Dear Buddies/Mentors/Guides

I am following this list from past 6 months but never posted my comment on
technical queries. on some general queries i answered.

now here i have some doubt and i am double minded in this regard. so i
would like to seek views from you Network experts to guide me and show me
the right way towards my journey to be a CCIE.
here is my query :-
I am having CCNA-RS and CCNA-Sec certification from Cisco. MCTS-ISA Server
certification from Microsoft. i have more exposure into routing n switching
as compared to Network Security. ratio is 70% into Routing Switching and
30% into Security.
1) Is it possible to maintain this 70:30 ratio?
2) i want to go straight for CCIE exam, that too within 2-3 years, is it
possible?, if yes then how?.- plz give me detailed guidance in ths regard?
3) Is it possible to clear lab exam thru self study rather than joining an
institute for coaching?
4) From where should i start? as i have all stuff(EBooks/Video Tutorials)
from cisco, INE, trainsignal, CBT Nuggets n other biggies in the industry.
