I've been brainstorming how to remember to RC during the school day without a noisy alarm wrist watch. I came up with two possibilities so far.
1) You could write "RC" or "Reality Check" on all of your binders or an item you use often (a pen or calculator)
2) You could use the bell system, if your school offers one, as a reminder to RC.

Note:These are just the results of my brainstorm. They are not tested ideas.

If anyone else can offer an idea or a solution they found please share it.
