Things happen in life that you can not control. Hopefully these happenings will be rare and sporadic throughout your life. Some of us have dealt with these things since childhood and are troubled by them today ..... I learnt early on to lose myself in drawing. In the worlds I could create and control and nurture and love. To hide and to be safe. As a child I wasn't aware of what I was doing, nor of how much I didn't see, but I believe drawing saved me from experiencing a lot of bad things.
Now, as an adult, I still retreat into my little worlds, to forget about lifes troubles, if only for a moment. Drawing is an escape. A release. It is meditative. It is a social and a private thing.
Never be afraid to show your work, people who don't draw think your work is great. People that do, can help you improve.
The others, probably dont matter anyway.
We all do bad drawings, even professionals. There are hundreds of bad drawings in us that need to get out before the good stuff.
Have confidence in yourself and your talents, no one is perfect, enjoy what you do and that will show in your work.
Don't agonise over every line, be loose and fluid, rough and sketchy, plan out the page. Clean up can happen later.
Be open to comments and criticism. Things that may seem hurtful (emotionally) could be the most helpful (creatively).
Surround yourself with like minded, creative souls. No matter what age/sex/colour/skill level a creative soul can only nurture another.
If you are able, join a class, or meet with a group, even if it's a few hours a fortnight.
Make time to be creative and not just in one area. Try other styles, techniques and tools.
