Many people tend to look at themselves and say "I'm not creative" or "I'm not artistic". The truth is however, we are ALL creative by nature - we are living, breathing examples of the creative process itself, and nothing can get you centered and help relieve stress like doing something creative just for the fun of doing it. Pick up a craft, a pencil, write something, draw, build - all of these activities are wonderful for helping us return to center.
Those who regularly engage in activities they find enjoyable - find life more enjoyable as a whole. By your very nature, you are designed to express your individualism, even though the media pushes on us all the stuff we are supposed to need/want to feel whole. Deep down, most people really long to just be themselves and don't know how.
Take some time today, and every day, to do something that is purely for your enjoyment that you have a hand in creating yourself. You'll enjoy the process and all the benefits that come with it guaranteed.
Don't have a creative hobby? Not to worry. Go to a hobby shop, look up a tutorial online, or just try your hand at something without formal training and see how it goes. Sometimes just the act of doing something new will inspire you to come up with new ideas.
