Takeaway: When in doubt, commit.
Most likely, this is how you will find your dream. Not by waiting around for a sign from the heavens, but by doing something and doing it with a degree of conviction and commitment that requires you to grow.
Call it a seasonal dream, if you want. Iterate on it until you reach a point where you know this is what you should do or not. Then go deeper, or move on. This will give you experience, broaden your skill set, and teach you the value of commitment.
