So many people say, "Oh, I'm not creative, I don't know how to sew." But really, creativity does not mean that you know how to sew, or know how to do any other particular craft. Creativity comes in many different forms.
Those are a few forms of creativity that I could think of off-hand. If you think of others, post them in my comments, and I'll add them to this list.
Obviously, one person can not do everything on this list. Each day God grants us just 24 hours. Time, money, and talent constraints are upon most everyone. Many of the above-listed forms of creativity can be simple (gardening--growing flowers in a pot or your porch) to elaborate (a yard with multitudes of beds and flowers). It all depends on how much time/money/talent you have! Growing a few flowers in a pot can be just as satisfying as a whole yard full of flowers! In fact, it's more satisfying to do something well in a small way than to half-way succeed in a big endeavor!
Sometimes a class is a fun way to get started, to learn the skill and to see if you want to continue on your own. Many stores offer classes--just keep on the lookout for them. Soon I'm taking a class in gardening at a local nursery. I'm really looking forward to learning more about gardening in this way!
Have fun being creative! Find some way that you can be creative, and you will feel greatly rewarded!
