In my case as a life time Sci-Fi fan I tried thinking and partly dreaming I was a person living on what we thought living on Mars was going to be like during the 50s like in old Robert Heinlein stories.
So my breathing mask became my Mars Explorer mask. OR the faceplate of my Spacesuit..etc.
This seemed to have work very well for me.
You might try thinking and guiding you're dropping off dreaming as a Scuba Diver Swimming mask or as a Fire Fighters mask or a Race Car Driver's helmet or a Motorcycle Helmet or something like that.
USING your SD Card:
I found it was too easy to forget to replace my SD Card, especially when I pulled it during the night, SO I now stuff my tissue into the mask whenever I remove it, so I cannot put the mask back on with the tissue in the way which reminds me to put the SD Card back.
I also learned to wait until my machines screen light goes out to help insure the card has been fully loaded.
And I always make sure to use the Computer's "Safely to Remove Hardware and Media" tool every time.
Lastly even thou I have not had any problems with unlocked SC Cards, with the new warning by Sleepyhead to lock the SD Card when inserting it into the computer and unlocking it before returning it to the machine, I now do so every time, and as that lock tab is hard for me to slide up and down I use a tool to do it and I leave that tool on my keyboard of arm rest in the way to remind me to unlock it when I remove it from the computer.
I will add that not all card readers will honor the lock and if it is not part of your computer like a SC Card adder. It has been said your should test this with clean SD Card locked and then try to copy something onto it, if the computer will not then your good.
