Sometimes it's uncomfortable for me to code anything because all I do is based on other stuff that is based on other stuff and so on.

Am I truly a creator when all I do is putting the puzzle pieces together so it looks unique?

I actually never honestly go beyond "modding".. Why do I always have to rely on other stuff working? And other stuff continuing to work for the following decade?

I thought it's only the case for software/web/etc but apparently most hardware projects are stuffing bought things together.
Music is stuffing chord combinations and melodies together.

It all goes on like that.
