We've realized that those fine lines are starting to set in, botox is becoming our best friend, and that it might be time to start "adulting" for real now. Here are 15 of the 30 Things Every 30 Year Old Should Know by the Time They're 30. From nailing the perfect skincare regimen to knowing the difference between forks on a dining table, the real lesson we learn is that we are still struggling at 30 years old. Who else has no clue how to access their 401K? We sure don't! Stay tuned for the other 15 which will be released on Lisa's and Jen's 30 & Not Thriving Podcast. We release new episodes every Wednesday at 10AM EST. Follow us on Instagram @millennial_girls for updates. Full video podcast on YouTube.
