Oh yea!
One reason why I love journals is that they are always good to look back on. Even if your last post was terribly over dramatic. It's a friendly reminder that we were all crazy and weird at some point in life.
Also, it's good to remember that the future will always hold surprises for you- good and bad. You won't know when they're coming (otherwise they wouldn't be surprises!!) so might as well embrace them when they do.
p.s. I get married in 4 months and 3 weeks. Eek!
