I suppose it doesn't really matter what your creative endeavor is, you need to make peace with it. The hard truth is we are not created equally creative. I can't draw a straight line with a ruler but know people who can sketch your portrait in just a few minutes. I absolutely love music, especially the Blues, but you know what-I can't carry a tune. Never could.
That doesn't mean we shouldn't strive to learn new skills and incorporate them into whatever our given talents are. If you don't grow, you stagnate. Some sort of law of nature thing, I suppose. Surely if I took voice lessons, I might eventually be proficient enough to overcome the shame of being booted out of third grade music class. Though I certainly would not become the next opera diva or rock star singer. So, I look for other things of interest I might be good at.
The amazing part is there are so many avenues of interest to explore. I found, over time, that being creative in the kitchen was not only fun, but useful. I have a fondness for rearranging my bookshelves. To be honest, more of a fetish. I love the feel and smell of real books. I do read eBooks occasionally on the tablet, but if it turns out to be a fave read, sooner or later the print copy shows up.
One of my 'when I retire' goals was to learn to quilt. So, before I retired and still had an income, I purchased my Bernina 830, known in my house as the 'Bitch', taught myself the basics and began a touchy journey of learning a lot about fabrics, threads, needles, and after a few bed and lap quilts discovered an intense passion for creating art quilts. I now have a row of ribbons, including a 'Best in Show' hanging in my sewing room. Those ribbons prove to myself that even though I'm not the most proficient quilter in terms of technique, I do have a talent for composition, color, and theme. Each quilt demands a creative effort and usually the learning of a new skill.
Another important 'when I retire' goal was to actually publish a worthy story. Stories have been in my head since a child and there many remained as other parts of life was lived. Almost a reality now, as Billy Dee of the Ozarks, an 88000-word novel is with an editor, and hope springs eternal for a January release on my 72nd birthday. If you believe in yourself, work at improving your skills in whatever you believe your talents to be, who knows how far it can go.
When you occasionally fall on your ass (and you will); Don't forget to dust your pants off.
