You never stay on one idea for ever, an idea is not eternal. You are constantly floating over knew ideas, you can either hover over them, capture them or dive in fully.
Being on the boat that is networked media, there is a comforting feeling in feeling uncomfortable in what we are about to undertake. There is no shore so there is really no need to panic. And if there was a shore in sight, then really we should be scared of approaching it, scared to be out of ideas.
Just a trust is what what you need to keep you going, keep you floating.
