The people closest to you will support you the least. It’s worse if you’re a writer because chances are you are one of the only people you know that enjoys reading. At best, those around you will purchase your writing just to say they did, but don’t press them on how far they’ve gotten because “haven’t had a chance to start” is quite possibly the answer. Their lack of interest is the reality.
The most frustrating part is that writers put themselves into their work which results in the work being the best way to understand the writer. The best way to understand how you think and what you find interesting.
No one cares as much as you do, because you’re the only one that cares.
