Always use "confident in" instead of "confident on". This ensures grammatical correctness and clarity in your writing. For example, say "I am confident in my ability to succeed" rather than "I am confident on my ability to succeed".
Common error
Avoid using "on" after "confident". The correct preposition is "in". Using "on" can make your writing sound awkward or ungrammatical.
