Creatives have answered the title question differently but, not surprisingly, some patterns that seem near universal emerge.
I have friends who say the hardest part is—
*Just getting started (as in staring at an empty canvas)
*Muddling through the sagging middle (this one is close to universal)
*Finding how and where to end (A talented friend struggles with this)
*Revising beyond a superficial dusting (This requires input from others, IMO)
*Putting your work “out there” (Many creatives never do because it is. too. blasting. hard.)
But worthwhile things are often hard. So this is not a complaint, but a list of blessings.
