In the computer industry, IT, IS, what have you, the entry level jobs are generally better than average, but they tend to keep you at that level and salary for a long time, unless you get out.
I manage a tech support call centerr for a software company, and the way to get more $ is either great patience, with 3-5% increases each year, or promotion. I didn;t start making any noticable money until i started to move into management.
Networking will be more money than the support reps i work with, but like has been mentioned, there are long hours and it is very competitive these days since in the past 15 years every college has a 2 and 4 year degree program and every yahoo who plays too much xbox thinks they are technically poriented and go into that field. I persoanlly think it is over hyped, for everone making good $$ in technology there are tons scaping by trying to get that great opportunity.
Like most things, the big factor is the individual, are you outgoing, easy to get along with, egoless, and ambitious? if so, you are more likely to get ahead than if you are extremely talented. Relationships with people AND talent are the biggest things here. Along with that , not missing a lot of work and prienting yourself to the job are big- i am constantly struggling with people who are skilled but not working toward the goals of the team, and prefer to do it their way, whcih cuts their effectiveness where it counts.
LAst piece of advice-- be patient and smart! if you are in your early 20s and not spending more than you make, and looking for opportunities to move ahead, you WILL be sucessful. Appease yourself with building your studio a bit at a time, but don;t let yourself get into debt over it, or anything else. I htink of it like a video game, where you have x resources and need to reach a goal to "win". if you look at it objectively, you will find ways to work the system. if you let short term desire put you in a hole, you will struggle.
as for studio gear and everything, knowledge is power. I get overwhelmed at how hard it is for a newbie to decipher the ad hype on new gear. Behrringer stuff sounds perfect for all studios if you read their copy. However tyot he informed, there are "bargian" items that are truly good quality (and hold value). Build your studio with stuff that holds value so you get something back for your investment when you are ready to upgrade. If you can't physically build a sweet studio right now, focus on learning the skills that you can use when you do.
