Even if you are not a marketer and never want to be one, you have a personal brand regardless if you have consciously designed it or thought about it or not.
Attention is the most scarce resource digital marketers have. The lack of attention is a core reason brands and even smart digital marketers are falling to lazy social spamming tactics. They are desperate for attention. As a result they foolishly believe that by blasting junk into our social feeds they will grab out attention.
Your intention may be good, but your execution may be poor and negatively impacting your digital marketing results if you are not earning trust and attention as a result of the right intention.
