cant remmeber to remmeber -_-

I always though and BELIEVE that I could remember...
I mean, at least I can remember that I have sthg. to do,
just sometimes I would forget what to do, the content, i mean.

But I just experienced so many times that I couldn't remember that I have to remember.

So.... I m now move up to a higher level of "forgetting"

Not even forget what I have to remember(the content),
but also forget that I have to remember to remember..

so...... should i start to tie some knots on my fingers
to remind myself that I have sthg. to remember?
