Who do you want to associate yourself with? Which sporting team? Or before that, which sport? Or do you think sport is stupid or for uneducated types? What type of car do you drive? Or what do you want to drive? Do you consider yourself an outdoorsy type of person or someone who is drawn towards the arts? What type of breakfast do you like to have? Why do you eat what you do? Do you like to go out and party or really just prefer quiet time at home? Do you have a particular political affiliation?
Just like a good brand, we position ourselves in our societies. We are all complex creatures but we have distinct values and patterns that make us who we are. It is very important to be authentic and not copy another personal brand that you aspire to become. Be you.
