I think there is a learning-curve when growing plants, particularly when they are house plants. Not counting my perennial landscape plants, all I grow are tropical plants. Orchids are my main interest and I have over 500 of those.
Keep in mind that most houseplants are simply tropical plants. Once you get the knack of growing one, generally speaking, the rest will be easy. Houseplants simply need the basics, such as strong, indirect light, moisture, occasional fertilizer, warmth, humidity, and air movement. The majority of houseplants are killed by over-watering, or more likely, having the potting soil remain wet for long periods of time. Most pest infestations, particularly the flying kind, can be prevented by having good air-flow. If there is a single one component missing when growing houseplants, it is "air-flow". Remember, what we are attempting to do is mimic Mother Nature.
I love the Tillandsia. I grow a few but have now limited those to native Tillandsia, those found in specific areas of Florida for example.
Here is just a sample of what I have in one area of one greenhouse. These are "baby" and "teen" orchids.
