Since you responded "occasionally" it appears you are sometimes apprehensive about mentioning new ideas to others. Keep in mind that new ideas frequently don't make much sense in the current order of things. Your self-consciousness might keep you in the realm of "what is" and prevent you from exploring "what might be better," hampering your creative achievement.
Sticking your neck out with a new idea means taking a risk, but without some risk there are few advancements. We've been trained since our early years to "make sense" and to "not look foolish." Logic, rational thinking and linear thought have been drilled into us. Even the standard IQ test mostly measures convergent thinking. But the greatest thinkers of all time were often divergent thinkers. New ideas often "don't make sense" and might sound "silly" or "wrong." Often, "crazy" ideas are a lot closer to "brilliant" than the same old tired "this is the way it is" ideas.
