No excuses. Do not be lazy
This is another two edged sword. While on the title we clearly mean that you need to look for inspiration in everything you see around yourself, in order to not lose the will to keep on exercising and working on drawing or painting, the activity itself should never be regarded as something that’s obligatory in any way.
This is a hobby, a free time activity which you use to keep yourself healthy, happy and motivated. Under no circumstance should you ever feel desperate or obsessed to keep on doing it, without eating or sleeping. Enroll in a class which has 1 or 2 lessons weekly or which holds weekend classes. This is the good quantity of exercise for you to be able to frequent the course even while you are working or going to school. As you are closing the stage when you will be able to work and paint alone, you can slowly start to collect all the things you need for your art work.
