Need some motivation🤦‍♀️

Guys I'm in a point in my life where I know what I want to do in the future but I have no Idea how to begin ! I'm just sitting wasting time while freaking out about my future! Is this normal? I MEAN is it just a faze ? I'm in my early 20s and just have no clue about my future. I feel like I should'v been way more close to my dreams by now but all I do is think about it and just get stressed .
