How to make sure your tastes don’t matter in one easy step:

1. Steal the stuff you like.

There. Done. Congratulations. You have achieved nothingness. What you like will now be less available in the future. (I hope you don’t like the stuff I like.)

How to make a difference (also in one easy step):

1. Enjoy the stuff you like through paid sources.

All the makers of the stuff you like have a chance to pay their electric bills because of you. Also, more of the stuff you like will be made in the future. (Thank you for your service to humanity.)
