Juggernaut and Saxen said it well, there's no secret, the only thing that will make
you better is:
practice,
practice,
practice,
and then,
practice some more
Look at inspiration by seeking artists or drawings in styles that you like,
visit sites like http://drawn.ca
and http://illustrationmundo.com to see many many styles, and COPY,
everyone needs to start somewhere, and by copying you can see
what have you been doing right and what needs to be corrected.
Don't try to start doing complicated stuff first, start with simple
things like a drawing a rock, capturing the light in it, using just paper
and a pencil.
when done, draw a glass, and when done, draw an orange.
but again, practice is "the secret".
I highly recommend, if you can, to take some art classes, that way you'll
know "mediums" (pencil, chalk, conté, acrylics, oils, even some sculpting),
and having a teacher to assist you is highly recommended.
Anyway, if you have questions, just ask, there are some artists in here
that will gladly help you
I took some classes while studying my career (graphic design), and will gladly help you
