Learn how to respect your initiative. It’s something we always forget to do. We take others ideas and vitiate our own. No doubt, ideas of others can be worthwhile, but why not try implementing our own first. How would we find out if our ideas were good enough, before even trying them out? But by trying them out our chances of gaining confidence on ourselves increases. If our idea fails, then we learn something. If on the other hand we succeed, we gain confidence. And confidence takes us a long way in life.
So, learn to accept your creativity. Use it and soon it will become an experience worth sharing. And as they say, speaking from experience is always powerful.
