Hi Guys,
I need your help. I am in my late 40's and have returned to study after taking about 9 years off travelling the world. I used to work for Netapp, and have had a few certifications in my past - but never Cisco.
I have come back to get back to work in a technical role, only to find I have pretty much destroyed most of my technical currency having been out of the industry for so long. So mid last year I started studying again, getting my A+, then my CCNA, and now working toward my CCNP.
I have a job - as a project manager in the food industry - which I really dislike. It pays well, but it is leaving little time to study - I do about 90 minutes before work, the hour for lunch, and about 2 hours at night. I've spent 6 months preparing for Switch, and going by the general consensus, Route will be that long and then some. Then Tshoot, and perhaps some security, cloud, and vmware, and I am looking at maybe 3-4 years to get back to where I think I need to be.
Or alternatively, I ditch the awful job, smash out 60 hours a week of study, and get 2-3 certs in the next year. I have some money put away that I can support myself.
What would you do?
At risk is not being able to get a job even when I do get all that learning under my belt, because employers prefer to hire employed people over the unemployed, or because I have no recent experience. On the plus side for leaving is that the job I am in is having additional negative effects on my life/health - no different from most people who dislike their working environment.
Am I crazy walking away from good money on a chance? Do I stick it out and part time study, or take the risk? I have applied for entry level tech positions at less than 1/2 my present salary, but no one is presently interested in someone who has been out of the industry for 9 years.
I see in other posts people being glad to have ditched the work to study for a job they want to do. But most people around me, including my spouse (and probably me) believes you should not leave a position without having another lined up. Or am I simply crazy asking for career advice on an online forum, with such little background information to base any real decisions on?

Is there anyone out there that has been in a similar situation? What did you choose to do? Are you glad about your decision?
