I Feel Inadequate

My friend was talking about her plans for future, of the exam she is giving in a few months, preparations and all. It's like she has her whole life planned out, she knows what exactly she wants from life.

It's now making me feel inadequate. I'm happy for her, but now i feel like i'm stuck here, i have no purpose, i don't know and i don't want to know where life is taking me. Like going with the flow. I've been fine with it in the last year and a half, life gave me a few nice surprises along the way too. But now talking to her makes me wonder if i should look for something, plan out my life, find something purposeful or meaningful. It makes me wonder if not having everything planned is worth it or not.

I have no idea.
