I'm 44 I was married at 23 and had dd at 28. I love my dd so much and would never want to be without her
BUT I look back at my 20's forward to hers and think absolutely do not settle down in your 20's!
Travel, try every different job possible, meet and interact with people from ALL walks of life, try every hobby possible, try foods and drinks and clothes and colours and music and films and tv shows
DON'T dismiss anything as 'I won't like it' UNTIL you've tried it!
I'm currently too ill to do any of that. I am hoping that when my daughter is in her 20's I too can do as much of the above as possible.
To that end you're NEVER too old either I went back to uni at 31, there were fellow students in their 90's! My mum is 67 she learnt to swim (fear of deep water) 5 years ago, an aunt learned to drive in her 50's
Don't restrict yourself life is for living!
To echo worra I've lost 3 family members under 35 and a few friends too (combination of illness accident and suicide) life is too short and unpredictable to waste!
Go for it!!!
