In my opinion, you're right.
'Secondo' — se-CON-do. Stress on the second syllable. 'Ragione' — ra-GIO-ne, stress on the second.
Use to introduce a personal opinion on any topic. 'Secondo me' is the most common and neutral way to signal that what follows is your view, not a fact.
'Secondo me' literally means 'according to me'. It's placed at the start of a sentence to flag personal perspective. Unlike English 'I think' which is internal, 'secondo me' explicitly invites the listener to consider your viewpoint.
Secondo me, è la scelta migliore.
In my opinion, it's the best choice.
Applied to a decision — very common in Italian discussions
A mio avviso, la situazione è seria.
In my view, the situation is serious.
'A mio avviso' is more formal — used in writing and professional speech
Dal mio punto di vista, è sbagliato.
From my point of view, it's wrong.
'Dal mio punto di vista' — B1/B2 level, very precise framing of perspective
Italians are opinionated and use 'secondo me' frequently without it sounding arrogant. Expressing personal opinions loudly and clearly is normal and expected in Italian conversation — silence or vagueness can be misread as indifference.
