Describe an important decision you made

The decision I want to talk about is turning down a job offer about a year ago. The situation was this: I was working at a small company, decent team, but the pay was low and there was nowhere to move up. Then a much bigger company offered me a role with roughly forty per cent more money. So the options were fairly clear on paper — stay somewhere comfortable with no path forward, or take significantly more money at a place I knew nothing about. Everyone I asked said take it, which, looking back, is partly why I hesitated. It took me about three weeks to decide, which is long for me. What changed things was a conversation with someone who'd worked there. He didn't warn me off exactly, but he said the team I'd be joining had had three managers in two years. That detail told me more than the salary figure did. Why was it difficult? Because there was no way to be right. Both options had a real cost, and I couldn't test either one first. And I'll be honest, part of the difficulty was that saying no to more money makes you look ungrateful, or unambitious. In the end I stayed, and six months later my own company restructured and I got the promotion that didn't exist before. That's partly luck, and I try to remember that — the decision was reasonable, but the outcome was not guaranteed.
