I do sometimes become self-conscious of my ideas. When it’s something I care very much about or something I am very confident about, I am much less likely to become self-conscious. Also, if it is a project or piece that I have continuously been refining, odds are the more I work on it the more confident I become with it. However, I do frequently become self conscious when my ideas start out and I need to develop them more.
I think the nothing-to-lose attitude can be very dangerous, and its not something that I would apply to my lifestyle. I understand that pros of it could be that you’re constantly pushing yourself to create more work without thinking very much about consequences but that in itself is a con. By acting like there is nothing to lose, I think one may become less careful and invested in their work, making it much less meaningful.
