While it was frustrating, think about all the crucial experience (business more so than technical) you gained. I would rather face a few bad projects early on to learn how to manage expectations, negotiate, handle sunk costs, and not get overly emotionally invested. I've had a project pulled from production a day after launch. Developing a thick skin is very important. If you are only thinking about what the project means to you and the payoff seeing it go to production, as opposed to the larger business concerns, you are being narcissistic and setting yourself up for failure. Conversely, a lot of decisions are imprudent and bad for the overall business and you have to know when to abandon ship.
