Well, good luck. Commission jobs are the WORST. Word of advice: get a contracted SALARY w/bonus incentives. I know you're young and can get sucked in by the numbers companies throw at you that you could earn, but trust me on this one.
It's my dad's financial company, so I know what I'm getting into. I've already been helping him out for 3 years. I wouldn't go work for an insurance company itself because I've seen and heard first-hand how that usually works out.
