Ok, I've read some really good, honest comments trying to help our young aviator. Make sure you absorb as much information as you can, and filter it for garbage!
I am a ditch driver, and a tundra cabbie. Both good places to build experience. But don't forget that you are flying the public around, and that requires a little more time. Don't be in too much of a rush to find yourself in an airplane with three generations of a family members behind you, on an icy ramp, with low visibility (500-2 my *ss!) and the wind ripping accross the runway. Taxiing seems to be impossible, let alone the take off. What about an engine failure on rotation? Tire blow out? Grandma sounds like she has TB in the back, the baby is yelling, and the dad is probably drunk. You and your few hundred hours have proven the skill to put an airplane in the air and back again, without bending metal.... but what about this? This wasn't covered in training! Have patience, grasshopper. There is wisdom in the system. The knowledge you gain in your quest will reveal this wisdom.
Never offer negative without the positive. That in mind.... check out the ads for jump pilots, banner towing, flight instructing, etc. It could save your life. These experiences allow you to find your limits, get scared once or twice, and not have to scare everyone else in the process.
Lab, Grant, Scenic, King, GCA, Yute, Hagelands, Inland and a hundred even smaller operators are waiting for you to get your 500 or 1,000 hours. It happens quicker than you'd think. Drop me a line when you get your 500 hrs, I'll see if I know anyone that can help.
Good luck!
ps... the first 500 hours is the HARDEST to get. Have faith!
