And if you block it, it will never exist through any other medium and be lost.

Not sure about this. I think everyone's got a set amount of creativity which they can partition wherever they want, and how they use it just depends on what they fancy doing. For example, I used to make and paint lead miniatures until I found the guitar - then all my self-expression was channeled through the guitar. When I picked up my fiddle again, the amount I played the guitar varied in inverse proportion to the amount I played the fiddle, and both suffer when I've got an interesting electronics project or when we need new plants or a new layout for the garden. Maybe that's just due to there only being so many hours in the day, but I'm sure only being able to put out so much creativity and imagination per day is a factor.

It is your business to keep the channel open.
