If you actually feel fine, then of course therapy isn’t likely to do much for you. The idea is if you’re feeling terrible enough to evaluate yourself, but it turns out you likely aren’t suffering from burnout, that doesn’t mean you shouldn’t look into therapy. Often people think they are suffering from burnout, but it turns out they actually have underlying trauma, anxiety, depression, etc. unrelated to work stress.
Everyone, even healthy people, should attend therapy if able. There's a lot of tricky ground to navigate as a person and you don't have to be experiencing trauma to get help.
