So, “…specification of an object…”. You’re designing something. Whatever you’re doing it should end with an output of some sort. Otherwise you’re staying in an endless limbo of ideas and half-finished products. It can be an object (say, a short film) but also an experience (say, a two day festival) or an abstract concept (rules for an RPG game).
Tip: Think about yourself as designing something even though it’s not a “regular” design like a poster or other art pieces. You’re also designing your own creative process, your career or even your morning breakfast. This way you’ll take smart decisions and consider yourself as the one in charge of constructing everything from everyday tasks to big projects.
