Your personal values inform your brand.
What do you value?
The question is not merely answered by
intellectualising or choosing from a list.
I have been guilty of doing just that.
So I can tell you that
What you think you value
What you actually value
Could be quite different.
The former is determined by
Your analysing neo cortex
The latter by
Your emotional limbic system.
Perhaps start with paying attention to:
What you like to read
How you like to write
What you like to see
Being mindful would give you a head start in finding your true personal values.
