After gardening for 55 years, about 2 years ago, I burned out on starting plants from seeds. Occasionally, I start something from seeds, if it's something I can't buy, but if I can buy the plant, I do that instead.

The constant attention needed by the seeds/seedlings, the long wait for a mature plant, and the high rate of failure, just doesn't interest me anymore.

Absolutely! Some year's I'm really into it, and then others not so much. Just go with it. Sometimes I think I won't bother in a given year, and then a month or so later, I'm ready to go. It's supposed to be fun - don't turn it into an obligation.
