What you should of told you mom was, "I'm sure you sucked at teaching when you first started too... But that's okay because by the time your ready for the nursing home I'm sure you'll be great at it".

I kid I kid... But seriously... No one is great at teaching when they first start. Everyone reads from their lesson plans or from the book and bores the crap out of their students at first. But instructing is also a learning process for you too. Not only will it force you to hone your people/communications skills but you will be reinforcing all the fundamentals that you will take with you and use the rest of your career. A lot of the guys I fly with now we're never CFIs and many of them are great pilots... But one thing I've noticed about old pilots is that they are very, very good at is knowing the regs. And you will get good at knowing them too as a CFI. And it will save your butt (and probably certificates too) one day.

As far as the 135 stuff being "entry level" your absolutely delusional. I don't fly 135 but I do have a job that demands a similar experience level. Just yesterday morning I had an attitude indicator failure, gear pump failure, and my emergency gear extension handle broke while trying to get the gear down. All at 3am flying in a valley surrounded by 12,000ft peaks. Not a fun time and not something I would of been equipped to deal with at 250 or 300 hours. There is more to flying than being able to control an airplane and follow a checklist. There are lessons to be learned through experience. Which a low time pilot simply doesn't have.
