What do people in their mid 20s do ?

Ever since high school finished several years ago, just been feeling sorta lost and confused like what are people really doing in their 20s who will soon reach 30s. Sometimes I see people in their early 20s who are more driven, smart and hard working. They already completed their education and even have high paying jobs and some are struggling with no sign of the future like what goals or ambitions. I really want to go back to college because I just hate working unskilled jobs. Seeing so many peers on social media makes me want to fix my life too. They have amazing relationships, exploring and creating memories. They have professional jobs. Like I too wish to fix my life but I feel it’s too late now.
