One feature of a type A personality is, apparently, “They tend to set high expectations for themselves, and may believe others have these same high expectations of them as well.”
In my experience, that quotation could be boiled down to the single word “Guilt.” As in:
“I looked at my bucket list again, realized how overdue I am projects I volunteered for, and now I feel like a disappointing jerk.
“And under that box of postage supplies is that kit my family bought me two Christmases ago because I said I was interested in building a cigar-box guitar.
“Not to mention the home repair work hanging fire.”
Thank god for the energizing power of egoist audacity!
