Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only for wallowing in.
I only recently discovered New Zealand's Katherine Mansfield, she was considered to be one of the best short story writers in her time. This from her journal which I read in Gayle Brandeis' book Fruitflesh...
We bought figs for breakfast, immense thin-skinned ones. They broke in one's fingers and tasted of wine and honey. Why is the northern fig such a chaste fair-haired virgin, such a soprano? The melting contraltos sing through the ages.
This beautiful passage brings figs to life for me. I might never eat a fig again and not think of her words. In cooking chefs learn to layer flavors otherwise the food tastes "flat". When I cook I think about how each layer is going to add to the final product. Is your writing layered? Add imagery to your writing through a blending of the senses.
Today try writing a few passages that are multi-layered. Consider that your character is eating a food they have never eaten before, how would you write the passage that would make your reader want to eat it. Now get back to work!
