Some people have always known what they wanted to do with their lives. Others make the decision of what they want to "be" in their college days.
And then there's the rest of us.
In my experience, life does not go in a razor straight line. In fact, if I were to draw a diagram of my life's journey, it would look more like the twistiest of pretzels. As we travel through adulthood, finding our path can be the most mind-wracking, soul-searching thing that we do. We learn, experience, and evolve, making decisions that shape who we are and the path we choose.
This is not an exact science, and for many of us, deciding what path to take a process that cannot be neatly packaged within 4 years of college, or even in your early adulthood. Rather, this journey can take several years of self-discovery, which never really ends.
Don't be hard on yourself if you are still trying to figure out what you want to be when you "grow up". With each morning we are given a new opportunity to develop our interests, learn about the possibilities, and take action towards the path we wish to take. If one direction doesn't work out, we have the ability to choose another, and another, until we hit our stride and start moving in the right direction. Finding your path can be your career options, but it can also be a quest towards spirituality, or the decision to find a partner and start a family.
That is the beauty of finding YOUR path, it is yours to define, yours to create, and yours to travel. Don't stop exploring, growing, learning, and living on your journey. Don't feel the need to compare your path with others, because others are trying to find their own way. Instead, run your race, putting one foot in front of the other, with the belief that in YOUR time, the path will become clear.
