1) Its not worth it.
2) Odd jobs are never going to truly supplement your income. Use them as a learning tool. Break even on your time if you can. Abandon them when you achieve your goals.
Success in IT...
If its not an intolerable thought, spend a small amount of time in the military. They will give you a free clearance and some initial training. This will put you in a position to contend for very nice paying contract jobs most can't qualify for.
Test all of the basic CompTIA certs immediately. They are cheap and low level. If you have difficulty by the second attempt at each, look at some brain dumps. Also, never list them behind your name. Just put them on the resume.
Grab a Microsoft cert. This is a necessary evil. Boot camp it if you have to. Even an MCP is better than nothing.
Read up on DoD directive 8570. This lays out which certs. qualify you for which government contract positions. It basically boils down to getting your CISSP or CEH to be eligible for the highest paying slots.
If you want to include Linux/UNIX in your portfolio, grab an LPI cert. Much easier to obtain than RedHat, and easier to maintain. Linux+ is good to have, but its just entry level, and as with any CompTIA cert, no-one who matters respects it.
A word on A+: It is a basic qualification for most State level jobs, but no longer garners any respect. Back in the mid-90's it meant something. Now, its like a high school diploma. You have to have it.
As for the diploma, its great for young people looking to get higher paying jobs right out of the gate. It also means paying back student loans, which results in a wash. Long-term, it means you can be a Manager. Managers have to prove their worth continuously, because they are a 100% overhead expense. They tend to have high stress levels and difficulty staying in touch with technology changes. They are the first to go when ownership or a contract changes hands. If you can handle the deception long-term, you can earn more than the talent. But, at a cost.
Certified professionals, on the other hand, only have to deal with the anxiety associated with the chosen ticketing system and established "procedures"/red tape, enough to drive any person insane.
Career paths for certified professionals...
If you go with infrastructure, and most people hate this choice, you can bypass all of the other certs and focus on network communications. This is highly profitable for those who achieve the highest Cisco certs, but only intrigues a small subset of the talent base.
If you choose programming, you can bypass most headaches in favor of development team interpersonal issues. Devs get a lot of freedom and usually enjoy their work. They get to go home at 5, and opt out of physical labor (racking and stacking, furniture moves, etc.). For this category, I would advise initial focus on Java. This language is the most widely sought after by recruiters looking to fill slots. And, learning the Oracle IDE (Netbeans), you can be productive in whichever language your employer demands in short order.
If you choose DBA, you get to be an invaluable asset with high pay, freedom and valued input. (Often a Manager without having to actually manage anything). Pretty sweet gig, if you like fooling with databases for a living. Look into SQL query statements and Oracle certifications to get your foot in the door here.
Sysadmins are going to be either Linux or MS based. MS admins are a dime a dozen. You'll be stuck in the 60K range forever, and there will be twenty applicants for every job you contend for. Have a MS cert, but don't rely on it. Linux experience will get your foot in the door for pretty much anything non-MS. People who do the hiring truly have no idea what the differences are between the various UNIX/BSD/Linux systems. An RHCE can easily get a job as an AIX administrator without ever having touched AiX (IBM). Don't bother learning or going after Solaris certs. Its in high demand now because all of the Solaris admins are dyeing off, literally. But, no-one will be using it in ten years because of the push toward standards in open source.
If I had to do it all over again, I would have skipped college altogether, and picked a specialization early-on. I wasted a lot of time and money along the way. Maybe you can benefit from this wisdom. I wish I had someone to tell me the truth back in the 80's.
