Decide today "I will die in GA". Then review the ways guys do:
1. Running out of gas
2. Pushing weather
3. Midairs
The first two are 100% in your control. Guys will buy a plane for hundreds of thousands and put it in the dirt overflying a field or unfilling the tanks to save maybe 30 to 50 bucks on a tank of gas. Had a guy run out of business in a brand new bonanza on a VFR day flying from south Florida to Destin a few years back...died in the crash of what I would guess was an 800k A36.
Weather--even with an autopilot, GPS, etc you are a single pilot with a single engine. Its not a turbine you can use just to overfly weather. Proceed with humility and caution.
Midairs--the heartbreakers. I don't have a simple answer, except clear clear clear and use SOPs at non towered fields.
While not 100% the case, most of the GA fatalities do not seem to involve professional pilots. I'm not thinking that's because we are necessarily BETTER, but probably are more likely to be doing this for fun and will leave the plane in the hangar on the days it looks ike work due to environmentals.
