Yesterday and today have been challenging. The reason is: I changed something and messed up. Change usually is a good thing, yet occasionally it isn't. So, when change throws you a curve, the only thing to do is correct the mistake.
The same is true with your craft. If something isn't the way you want, go back and do it again and if necessary, again.
Knowing your equipment and materials is crucial. Practice. You have to know what you are doing to do it well. What happens, over time, is the knowledge is absorbed and becomes part of you. Then, creativity is free to play and experiment.
Today my Photography Muse is on vacation. She so enjoyed our vacation, she may still be in Pennsylvania. To encourage her return, I will play with photography, painting, pasteup and alter some of my images dramatically.
Suggestion: Play with your craft today. Do something fun.
P.S. Will post altered images later should anything spectacular show up!
