I keep a small desk essentials kit at my work desk so that I don’t have to carry items back and forth from home constantly. I keep some loose leaf green tea along with a tea infuser, and some dry snacks. At my job there is a kitchen with a microwave, an electric kettle ready for employees, so I base my small kit on the available resources. In my bag which I do carry back and forth from home, I keep a stainless steel travel mug, and a set of utensils along with a fabric napkin. The reason why I keep my utensils and coffee in my bag is due to the fact that I like to be ready to go out to eat when the opportunity arises. I also will use my coffee mug for coffee, teas and water as well.
The variable items that I tend to carry is my stainless steel water bottle, whatever lunch I’ve packed for the day, and my “to go” breakfast which is usually oatmeal in a small mason jar. Depending on the days schedule or how much time I have before I step out of the front door I may or may not carry along the variable items.
