You have all your supplies at the ready; now it's time to do something with them. Many painters often ask when is the best time to paint.
Do you have a time of the day when you feel more fresh and creative? That's your best time to paint. Ideally, what you're looking for is regular, uninterrupted time you can devote to your art.
Even if it's only for ten minutes, paint every day. You'll be surprised at how much you can accomplish with ten-minute sets of time. Ten minutes is good for quick exercises and planning. Increase your painting time as you can.
To encourage yourself to paint every day, set up your paints and leave them out. Packing and unpacking supplies sometimes is enough to make you avoid painting. Find a spot that you can devote exclusively to painting. Using the kitchen table isn't good because you eventually have to pick up your paints so you can eat dinner. But if you have a place where the paints are always ready, it's easier to take ten minutes to paint.
If you're having trouble finding painting time, look for a local art association that conducts classes, and sign up for a regular class. Then you're assured at least that class time every week. An added benefit is that your instructor and classmates can provide inspiration as well as instruction.
You can set your schedule to accommodate your needs. If you're lucky enough to have lots of time, you'll be surprised to see how quickly time goes when painting.
