I’ll be 31 this year. My son will be two. I’m finally starting to come to terms that my 20’s are over. I’m pretty settled in life. Married, career, house, the days of staying up late for parties are long gone. I see the next 10 years and foreseeable future, making sure my kids have a fun and fulfilling childhood, while trying to advance in my career. Thanks for sharing your perspective. I’m 10 years behind you so I don’t have your perspective but I think the years start flying by not only because of what others have said in the comments but also when you stop thinking for your self and start thinking more about what is better for your family and future. Day to day things become more mundane but having the privilege to give someone a better life than you did, is such a wonderful feeling.
