✕Common Mistakes
J'ai agi en me préparer à fond.
After 'en' you need the present participle, not the infinitive.

The preposition should be 'en' for the gerundial construction.
J'ai agi en me préparant de façon à fond.
In very formal contexts, replace with 'de manière approfondie' to avoid colloquial tone.
