The phrase "arrive early at meetings" is understandable, but the more natural and common expression is "get to [place] early." "Get to" is a phrasal verb that is used more casually in everyday conversation, and it sounds more natural. "Arrive" is more formal and not as commonly used in casual contexts.

I a'm an anxious person, so I canno’t help takingbut take action early.

The expression "can't help but [verb]" is a more common and idiomatic way of saying "cannot help taking [action]." It sounds more fluid and natural. "Take action" is also a more concise and natural phrase than "taking action."

The other day, I arrived at destinthe stations an hour earlier to meet up with my family at station.

"Arrived at destinations" should be "arrived at the station" because "destination" is too vague here. You are referring to a specific place (the station), so "the station" is the correct and clear term. "A hour" should be "an hour" because "hour" starts with a vowel sound, so the indefinite article "an" is used. "At station" is missing the article "the." In English, we use "the" before a singular, specific noun to clarify that we are talking about a specific place.

I know I amight seem a little strange.

The sentence "I know I am strange" sounds too self-critical. The correction, "I know I might seem a little strange," softens the statement and makes it sound more natural. Using "might seem" makes it less direct and gives the speaker more room for self-expression without feeling overly harsh.
