What has been your biggest adjustment from childhood to adulthood?

I think my biggest adjustment is learning that life doesn't always pan out the way they do in our dreams. People don't live forever, rent is high, and people can be ruthless. My timeline for having my dreams fulfilled were very unrealistic. I wasn't spoiled so I know it takes hard work to get what you want and I like being able to pay for my own things; even though sometimes I rather buy shoes then pay a bill on time, but when will I get "there"?? I like to be on a schedule, but I've been embracing and enjoying the journey to wherever "there" may be and building tough skin along the way.
