What are you waiting for?! Writing is one of the best gifts human beings are gifted with! It helps you psychologically and intellectually! It helps you calm your nerves, and helps you to think better. Years ago, I read somewhere that when a human writes, his/her mind and body coordination improves because it is a very tangible form of expressing what’s going on in one’s mind and heart. Nothing else is as tangible as writing (one can express his/her thoughts through singing, acting, emoting, etc but they aren’t tangible forms). So, what are you waiting for? Good luck with whatever you choose to write! I am sure you will pen down great thoughts and topics. Good luck!
