Stand next to a plant that looks bright, and green, produces something (in theory) that you might eat. Say hello. Do it in your head, if it makes you feel less silly. Feel less silly, anyway, when the person standing next to you is also talking to seedlings.
If you can only have one plant in your house, make it an aloe vera. It has countless uses for health and wellbeing, and is edible too!
I've discovered that there are plenty of food plants that can be grown indoors during the cold half of the year, and few require any kind of special equipment.
