Inspiration is kind of different for each one of us. Every person/artist has a different way of working and finding the triggers/inspiration for the pieces.
My number one trick for inspiration ia having your eyes and ears open! It’s all about the everyday life. If you do, you can catch the beauty, the images, sounds, colors around you.
And then there are the details that some others might not notice. A small detail can be the starting point of a piece of artwork. A detail in your environment can start a series of thoughts and feelings that can lead to creation.
Yes, time, is crucial. You can never force inspiration. It needs its time, your brain has to proceed information and make something out of it.
But, in the meanwhile there’s one more important thing that can help: work! Even if you don’t have the perfect idea (or no idea, it happens sometimes) in mind one day, you should still sit down and work.
Inspiration doesn’t come out of the blue, on its own. Needs a little help and work can never do any harm! 😉
