Don't try to be more personal
The persona's you're working with probably don't include someone who is visually impaired. Your persona's are probably all white, young and/or dynamic. None of your persona's went through a tragic event recently.
Be careful when creating emotional experiences for the lucky ones. You shouldn't congratulate everyone with another great year, and/or a better year to come.
Don't try to be more personal than you (or your system) can be.
