Good Lord! Someone asking me to post my best advice. For those that don't spend time around me in my daily life, you know this could get scary, but here goes:

Be yourself. Yes, a common and seemingly conception but most try too hard on occassion. Try and just type out as if you were actually speaking. You will find yourself working to think of things and focusing to REALLY put forth some effort. What seems so simple could indeed be a challenge to the most prolific blogger/steemian.
