El,

135 freight isn't entry level as a job goes, but would be great exposure for some to experience from the right seat. When I was in it, I took many folks for "rides" on my freight runs, both for the experience, and usually they bought me dinner too!! I know a few that have since gotten airline and other 135 jobs.

With any career, you need to earn your experience. Electricians and other skilled trades do apprenticeships. I really wish aviation had this, because honestly a 4yr degree doesn't cut it IMO. You have to have that real world experience to offer, and know where you are lacking. Until you fly to earn a paycheck, you're just ignorant of what it takes(and its not to flame you, it's just the way it is for everyone).

So if you can, take on the CFI the best you can, teach the best YOU can. Honestly, time to separate from mom if she can only tell you what you are doing wrong, and not helping you. I don't know if its been said here, but you will learn just as much or more as a CFI than you did up until the point you started teaching in the real world!

I could go on and on, but my last piece of advice is this.....

Whatever you do, whatever your job or skill level, always challenge yourself to perform better. No one is perfect, but we can all strive for that goal, and let it drive you.

Best of luck.
