To blog is very simple honestly it's as simple as creating a site account on whatever blogging site you choose we personally we like to use WordPress,blogger,Kofi,steemit and Patreon.
Then find your groove by talking about hobbies passions experiences games kids teaching and voice by being honest thinking before you post keep it lighthearted and fun but be yourself above all else and make your presence known by adding content with schedule photos videos graphs but be consistent kind and respectful and connecting to others who blog like you your friends family and community.
