In this case, he/she is probably referring to dealing with things before they have a chance to turn into big issues - remembering to buy toilet paper when you're almost out, picking out clothes the night before when you need to be up early, actually getting enough sleep / exercise, etc.

Uncomfortable and boring sometimes, but you can avoid a lot of stress by catching things before they turn into big issues. Of course, if you thrive on drama, then making a habit of ignoring things until they blow up in your face will feed the fire. (Know anybody like that?)

I think the people at my old Aikido dojo called this "zanshin".
