Here's a woman who had the Write Stuff for life!
Eleanor Roosevelt was a role model full of sage advice who personified a life of leadership and accomplishment. At seventy-six she wrote a simple guide aimed toward living a more fulfilling life, titled You Learn by Living: Eleven Keys for a More Fulfilling Life
One of my favorite quotes from her is this:
"No one can make you feel inferior without your consent."
When it comes to writing, I've discovered authors often have to deal with insecurity issues (no, I don't mean YOU). In my opinion (here's hoping you'll agree) it's because we spend countless hours laying out a story that is near and dear to our hearts...then we have to wait...and wait...(possibly FOREVER)...for any feedback or affirmation. It's the same with many of the arts.
But no one artist or author will please everyone all the time (not even you). You can only focus your effort on putting out your best story every time. When you strive for consistency, your confidence will grow (yes that does mean YOU) lending momentum to the areas that matter most to you and your publishing goals.
As you move forward with your writing career (or any endeavor) there will be things to learn and try, and the good news is there is always someone out there to help. If you don't understand something it doesn't make you inferior- just ask questions, do the research, and ask some more until you get the info you need to take yourself and your work to the heights you dream of.
Happy writing and learning!
