If you do see it shrivel and water, that is a fair enough way to start to learn about these plants, but go one better, and keep track of how long it took from last watering to when it began to shrivel. Then water one day sooner
Water needs change with winter and shorter days, because it gets less hours of sun, and it grows more slowly or not at all. Turning on the heat leaving the air dryer, can affect watering.
Just keep a watchful eye on your plant. When it is freshly watered, pick up the pot, feel how heavy it is. Remember it. Then as it is ready to be watered again, and good and dry, look at the plant carefully, does it look different to you than when it was freshly watered, is it a bit dull? Pick the pot up again, and notice how light it feels. Remember this as well.
And finally, if your just not sure, If in doubt wait a day or two to water.
