When you can't use it
- たものだ is for a habitual or repeated past viewed with nostalgia, not a single past event. For one completed action, just use the plain past (昨日泳いだ, not 昨日泳いだものだ).
Easily confused with
〜ていた 〜ていた neutrally reports a past ongoing or habitual action (毎日走っていた = 'I was running / used to run every day'). たものだ adds a wistful, looking-back-fondly tone that ていた lacks. ものだ Non-past ものだ states a general truth or social norm (約束は守るものだ). The past たものだ means 'used to ~' — personal nostalgic recollection, a different function.
