I used to consider myself unartistic. I admired people who can draw and play instruments. I just never counted crocheting, needlework, or another thing I did as art. They are under the craft category; I understand, but you must have artistic nature to make things look beautiful.
A friend introduced me to painting. Now I am hooked ;). It is probably all that needlework I already knew. It is as simple as peeling an onion. Sometimes your eyes will tear up with frustration. Just like in life when you are inexperienced and navigates the turbulent waters of school, sports, or how to be in love. It takes work and some preparation. Only with continued efforts and discipline, you can find the confidence required to create a masterpiece.
Soon you will be looking at colorful landscapes symbolizing your memories and your taste. It makes you tired, yet satisfied. It will change your mood and even your self-esteem. It takes courage to paint and share with others your work, yet you will notice how an emotional connection with your viewers will flourish out of it. Colors make everything happier. People will admire an abstract or realistic painting as they feel.
You cannot pretend to walk before you can crawl and much less run. Your little legs must develop the calves to support the weight of your body. The same way your hands must learn the strokes. It is not impossible! Painting can be taught, unlike having to be born with a gene to playing an instrument. Find the inspiration through any venue you have available. After you have the inspiration, start preparing.
Feel it in your heart first. Then you will be able to sketch it on the canvas. Dig into your inner soul and let the power of storytelling inspire you. It will not be perfect at first, just like when you ride a bicycle or have the first crush. You will remember the mistakes you made choosing the colors, the type of canvas, or the brush. Muscle memory will help you to be selective and avoid mistakes.
Apply these principles to your life. Do not be too hard on yourself. It is a process you must enjoy if you want the perfect end.
