Those birthdays with a zero in them can be quite daunting. Almost everyone has that experience at some age. It's a good time for self-reflection. Ask yourself where you are in terms of where you thought you would be at this age, and think about whether those goals still make sense for you, and what you think is best for you now. Don't be too hard on yourself though. Remember that the process of reaching your goals is just as important as the goals themselves. Most of life is a process, and it's important to enjoy the process. Happy Birthday!
