Now I am asking a lot in this. And suppose I flake out - suppose it turns out I am a bad teacher, or burnt out, or lying now. So then you would put the effort in and have been duped. And your effort wasted. Even if I were a fraud, no effort is wasted.
Education is essentially self-education when it comes down to that.
On the other hand, if you're burnt out, and you don't feel like making an effort with someone who apparently hadn't made the effort all along, you can dig your heels in and not make the effort. That is your right, and your anger or frustration is justified. But think about it. If the effort rewards itself whether or not I come through, the refusal to make the effort is a certain defeat no matter how proactive I become now. So it only seems logical to roll up our sleeves and see what is possible.
