At first try to find out what you like to make and then it's just trying to pick up your skills.
There are so many things: clothing decoration amigurumi potholders and so on and so on.
My opinion is to start with something smalll (depending on your skills earlier)
When I hit an idea drought, I revisit an FO, look up the pattern on Ravelry and lurk through fellow creators' projects. As we have this one project in common, I often stumble upon other patterns and colour schemes that tickle my fancy. This will usually sober me up from feeling overwhelmed.
