If you are a creative person, create!  Waiting for other things to happen....such as.....the kids to grow up,
a room to create in, once your roommate moves out, etc. etc. only delays your personal growth. You grow
a little bit more each time you stretch a little bit....creating something that is uniquely yours. Sketching requires lots of practice. If you're not ready to call yourself an artist yet, then say you are "practicing". Take
art classes. If you aren't able to do that, get sketching books that will take you step by step.You'll soon see
that you have progressed further than you thought you would.
