You're defending it because you've already spent five years on it
“I've already spent five years on this.” So you've decided to spend a sixth. Excellent plan. If the first five were a mistake, you urgently need to make it more convincing. You say this about a job you hate, a relationship that's been empty for years, a project kept alive by transfers from your savings account. Asked why you should continue, you tell the story of how much you've already invested.
