What to do?

So this coming semester, ill be doing general education courses to transfer them to my local state school. Until then i will be self-teaching myself mobile app development. But I also want to learn cybersecurity. But I ALSO want to resume web development as I will be transitioning into back-end technologies such as NodeJs, reactJs, etc. There’s SO MUCH that I want to do, but idk what I should focus all my energy on! Like I really wanna do mobile development as I feel its less common than web development, but I also want web dev under my belt too! Idk what I should do… 😣
