More than a publication is an excellent reflection. Time is life and if you dedicate time to an idea you are dedicating life, if you share that idea you are sharing your life. Your life, your time invested in that idea can fulfill a purpose in those people with whom you have shared. Fear is the worst emotion, but like all emotion, fear is also momentary, it is not bad to feel it, you just have to reflect on how to act in the face of that circumstance. The opportunities are for everyone equally, it's up to you to know how to take advantage of it. Do not be afraid, share your ideas and you will be investing your time, your life well.
