> I wanted to send a quick note. Got the magic number in San Jose, CA

> started to get seriously burned out. I guess that's when you know
> you're ready :) My first attempt was on token-ring/IPX/etc.. So it's

> Thanks to everyone! I'll elaborate :)

> Groupstudy has been very helpful. I found that trying to help people,
> althought I didn't do it as much as I'd like to have, really helped me
> learn in return. Many times I knew 80% of the answer someone was
> looking for, which forced me to do a little research before I responded.
>
> Brian's McGahan and Dennis, you guys are great. I can't think of a
> better compliment to have than when a CCIE hopeful like myself starts
> using your names instead of technologies in the search engine :)
>
> CyscoExperts. You guys were very motivating for me. Being able to get
> away from work for a week, plus having folks around that are so
> motivating that you actually want to come in every day and lab for 12
> hours is amazing. Your class is addictive and I found myself wanting to
> stay another week and being willing to pay for it, just couldn't swing
> the time off.
>
> Doyle, Caslow, etc.. Good books. When you read the standard reading
> list and everything makes absolute sense, you're doing good. If it
> doesn't... Don't blow it off. Read other material and mess with stuff
> until you get it.
>
> Gordon Hughes for his wonderful motivation throughout. Same for Jim
> Phillipo. Having a few buds that "feel your pain" meant the world to
> me.
>
> My wonderful girlfriend Melissa for being ultimately motivating and
> understanding. Whether it was me being a troll in the study cave (and a
> mean one when I was frustrated), or me playing Warcraft when I should've
> been studying but was burnt, you dealt with it all like it was no
> problem.
>
> NetMasters DoIT and IPExperts gave me a lot of great labbing material.
> I really appreciated the "Spot the Issues" section of DoIT labs. It's
> nice to have an explanation of what's going on.
>
> Take care and good luck. I'll be lurking on the list and will respond
> if someone doesn't beat me to it.

> Maybe so, but it never hurts to ask about anything you are planing to
