a sunny day. the rainbow in bubbles. the sound of chimes in the wind. a strawberry ice cream cone. diet coke. iced tea with lemon. the smell and taste of morning coffee. picking dandelions just to show someone you care, etc.
What's the rush to get married? To have kids? Enjoy your life. Do things by yourself. Learn who you are. Travel. Enjoy your 20s before you settle down. Life may be short, but it's the longest thing you'll ever do. Don't rush. Make it right.
