Some of these (from another thread I answered a while back) overlap with EdwardH, but here you go anyway:
You can fast from entertainment (TV, music, Internet), you can sleep without a pillow, you can leave the air conditioning off in your car when you are alone, you can wait a few minutes to put on a sweater when you are chilly, you can leave the good parking spaces for someone else and park far away from your destination, you can leave your uncomfortable shoes on for a while after you get home, you can sit in the uncomfortable chair so others can use the couch.
At meals, you can eat more of the foods that are not your favorites and less of your favorites, you can leave off salt and pepper or condiments, you can take the least attractive serving of food on the platter so you leave the better ones for others, you can eat whatever is set before you without expressing a preference.
In your relations with others, you can take every opportunity to humble yourself. You can keep clever comments to yourself, you can omit telling the perfect joke, you can make sure you never interrupt, you can smile and give your time to those who irritate you, you can do little acts of service for people without calling attention to them.
Hope you find something helpful here!
