Sure you do - when you make a sales presentation, ask for a raise, or interview for a job. Marketing yourself can be showing up on time or ten minutes late.

Marketing can be in the color or where it is placed in the store.
Have you ever noticed the gum and candy so conveniently placed by the checkout in the grocery store. Look at the colors and packages used to sell snack food compared to potatoes or bread.

Attracting what you want, rather than chasing after it.
