Flying is as safe as you make it. These accidents we all hear off are mostly pilot induced by poor decision making and cockpit management, not all but most!
Some people you see flying does totally worry you but you need to ensure that you prepare yourself before every flight and ensure you have checked all the details, met, NOTAMS weight and balance etc.
You need to be thinking ahead of the aircraft and always be looking around you for that forced landing site other aircraft etc ( plus enjoying the view!!
, it will become second nature after a while!
Above all enjoy it do all your planning and your be fine!!
Best of luck!
