Microsoft? Cisco? SAP?

Dilemmas....I'm forever in dilemmas

When I've finally convinced myself to take up Cisco Networking...my poly frens told me to think properly..would I want to do Networking for my whole life and do shit shift work..irregular hours...on standby 24/7...#*$&^#*%^...
Thanks huh...made me re-consider again

Then one of my vendors say "go study MS Server 2003"...then I think why not...went to check out the course...bloody h***...so many modules to clear.

Then Anne say go study SAP...be consultant...earn big bucks...but the cert cost $14K....WTH

How can I...a poor employee...afford...sigh~

FUTURE BLEAK ONCE AGAIN....
