You will find that there are a lot of different ways to sketch and draw. This is due to the way that technology is being used now. If you get really bored and do not know what to do, but you do not have money, you might just get simple things like a scratch sheet of paper and a normal every day pencil. Other people might just use a website that focuses on sketching/art. For me, personally, when I sketch online, I use a website called sketch.io. If you wish to assess it, you may go here to https://sketch.io/sketchpad. Below, you will find some images that were created using sketch.io. I consider these kinds of images inspiring and moving.
Others like to use other websites or forms for sketching. Feel free to search the internet for more ways to sketch. Weather it be online or on a sheet of paper, there are many ways by which you can have access to ways by which you can express both your mind and your feelings towards anything. If someone won't listen to you, paper will!
