If your goal was to win money, then this fold was certainly a huge mistake. AA all in preflop is always hugely + chip EV regardless of the number of opponents, and as others have already said, the only time, this can be overridden by ICM-considerations, is near the bubble in a satellite. Had you called and won this hand, you would have gotten a huge early chip lead, which allowed you to comfortably reach at least the middle phase of the tournament.
If you had other goals like fun or entertainment for the weekend, these are personal and therefore not suited for discussion in a
poker forum. I can not tell you, how much it would have bothered you to go out in the first hand. I can only tell you, that if your goal is to win money in tournaments, you have to always be ready to die, and you can not let other factors than chip EV and ICM influence your decision making.
