I don’t know what to do

I wanted to make a project for stardance hack club but I don’t know exactly what. I know a little bit of almost everything because im not decided what I want to really be good at yet. I know cpp pretty well, little bit of c#, some php, html, css, js. I also know basics of CAD, I like arduino, desktop apps and web apps. I don’t have any idea for anything that isn’t already there and is interesting. Pls help me submitted by /u/Blazej_kb [link] [留言]
