Being responsible, keeping your word/having integrity, being reliable, in control of your own destiny, financially independent or close, pubic hair, having to sing about women, not girls, appreciating the feeling of boredom because it means you aren't working or having to do anything, slowly losing your health as time goes by, looking in the mirror and seeing someone older than you conceptualize in your mind, paying sh***y bills and taxes, dealing with tedious miscellanea in the day to day with equanimity...
