Move a seedling outside too early and the first cold night takes it out. Let things root first.

New things are fragile in a way that has nothing to do with whether they are good. A plan, a habit, a friendship needs a period of low exposure before it can take weather, and too much exposure early kills things that would have been fine with a few more weeks. Fragility at the start is normal, not a verdict on the thing itself.

Keep the new thing small and mostly private for its first stretch. Show it to few people and test it against mild conditions. Strength does arrive, but after the roots rather than before.
