Have you ever had an idea that you panned a the time… then coming back to it later with “new eyes” find that it was actually great?
Like to start a blog… but not knowing what to write about… or to write a post on a controversial topic, but putting it away. Maybe the idea isn't bad, it just needs to incubate. It needs to develop.
Don't discard all your ideas. Save them. You never know when they'll come in handy and even with new experience and a new perspective, they might even be brilliant.
