Lack of passion in my life, possibly stemming from TV

Throwaway account for reasons.

I was watching a tv show the other day, and something I always notice is how passionate the characters are. Everyone seems to stand for something and have an intrinsic motivation. That's when I realized that I don't have this. I'm doing really well for myself and am happy, but I feel a bit empty. There's nothing that I feel strongly about, and nothing I really stand for. I just seem to have a hard time feeling anything that isn't generally debauchery. I make all my decisions off boredom, and not being bored is the only thing really driving me. I feel like Meursault in The Stranger.

Any advice on this? Maybe just stop watching tv because it causes unreasonable expectations?
