Obligatory Joke: OLD? That’s not old. I have ties that are older then 23 years old!
Seriously, I do.
23 is not too old to be in college. I have a friend who completed two years of college by the time he was 21, dropped out, worked for 25 years, and completed his BS at 46, his Masters at 49, and is now nearly finished with his PhD.
And I have other friends who had dropped out of college by 23 and never finished. Not to mention all those many people who never attended college in the first place.
Be proud of your journey through life. It is yours. Without your journey, you would not be who you are. Besides, ten years after you graduate, you will never look back and think that you graduated “too late”.
