Writing is a puzzle you'll spend your lifetime unlocking. You will never know it all; you will never know enough. You can always be better, and figuring out how to be better is part of the thrill and joy of the job.
I earned my writing stripes with a large man's shoebox overflowing with rejection slips... more than 100 before I got my first, 'Yes, we want this,' accompanied by a check.
Don't talk about writing. Write. Don't show unfinished work to anyone. Don't show finished work to non-writers. Get your opinions, not from friends and family, but by sending your work out to editors. An endless stream of rejection slips means you need to learn more. So learn more.
Fiction---good fiction, anyway---is dream made flesh, given purpose and drive, and set on a quest to show us the best in us and to give us the power and the tools to dream beyond reality's 'merely good enough' to a vision of what is truly great... ...and then to give us the stories of men and women of character who in turn inspire those of us who dare to reach for the truly great within ourselves. THAT is why you write fiction.
Anything designed to be inoffensive isn't worth your time -- life itself is pretty offensive, ending as it does with death.
