2. A writing implement - "The dullest pencil is better than the sharpest memory," so sayeth Mark Twain. I agree with him. A pen, a marker, or the dullest pencil must be found in your bag. It's essential for scribbling notes, important reminders, and phone numbers. These days, a phone often replaces the pen. However, the pencil/pen has a certain advantage: it is not prone to having low battery.
3. A small notebook - A necessary companion of item #2. Writing on your palm will do in some cases but can be a messy affair. Nanay would strongly advise to pack a notebook for keeping the most essential information intact.
4. A tube of lip/cheek tint - According to Nanay, this has got to be the most important item in your bag. To be used for quick touch-ups, especially during times when you don't have access to your full makeup kit and you don't want to appear as haggard as you feel at any time of the day.
5. A reusable water container - This is in the bag as an ecologically friendly alternative to all those disposable cups and bottles we tend to use then throw out on any given occasion. Mine currently is a KeepCup I got from Nanay.
Are any of these items in your bag?
