Statistics is one of the three worst lies!
You can train yourself sure,
What happens if you are wrong...
its just too expensive to learn everything on your own flesh (in time, effort, love, craftsmenship, work, problem solving, money).
there are many small but important things you learn from experienced instructor, like five=5 checks on the radio before takeoff [

]
or that all the flight is actually planed ahead...
if you try to takeoff first time without instructor at the field it sounds like: "WOW everybody stop everything you are doing, come and watch this"
Good luck
