If you want happiness through writing, write only for yourself. Never check site visitor analytics, comments, shares. Only care if you're enjoying the writing. To make it easier you can also write under a pseudonym.

Some of my worst habits formed seeing early posts go viral and then getting addicted to that endorphin hit. The amount of time I wasted checking analytics and new subs would probably equal the time it would take me to write 10 more posts or read a couple books.

But congrats at sticking to it for 10 years!
