Practice Drawing Hands and Feet.
In my opinion, the hardest body parts to draw are hands and feet. Many artists fail in this area simply because they spend most of the time on the body but leave the hands and feet for later. Spend some time each day studying hands and feet anatomy and structure. You don't even need a live model-just draw your own hands and feet from different angles.

Practice drawing human anatomy one hour a day
If you're like me, practing anatomy may seem like a daunting task. But it doesn't have to be overwhelming if you just keep it simple and practice one hour a day. Choose an area to focus on and fill a whole page of detailed anatomical studies of that area. Make sure you have lots of anatomy reference books and photo references at hand.
Practice six days out of the week and give yourself a break on the seventh day.
Buy the end of the year you will be amazed at how much progress you've made.

Make sure to stay consistant and stick with it for at least a year. One hour a day is a piece of cake.

Lets say you sit down at your table, ready and eager to draw, only to realize that you can't seem to get into it. You can't seem to find that magical flow that usually happens, that point where all your creative ideas come leaping out onto your piece of paper. Your stuck. It happens to all artists at one time or another.
Sometimes we run into a wall and it seems like the harder we try to push through, the more difficult it becomes to think of anything worth drawing. Sometimes it lasts for days. The wall becomes thicker and thicker until we are ready to give up. There are a few things you can do to break the block. These methods have worked for me.

1. Step away from your art table and go for a walk. Take a break. Put aside your art projects for a couple days. The worst thing you can do at this point is force yourself. Go to the bookstore, museum or art gallery. Watch a good movie or read a book. Hang out with your friends. Get inspired by all the different images around you. Don't worry about your art. The ideas will flow naturally and before you know it, you will be back at your art table with fresh material.

2. Make studies first.
Make studies in the area you need help with. If you are having trouble with color, than make color studies. If your problem is perspective, than pull out the old perspective book and start sketching some perspective angles. If its anatomy that you need help with, try making some anatomy studies first before dipping into your final character drawings. You will feel more confident about your art and more certain about what works and what doesn't.

3. Try this fun exercise.
Pull out a piece of paper and pencil. Close your eyes and start sketching. Don't try to draw anything in particular--just scribble until you feel like you have filled the whole paper with random doodles. Open your eyes to look at your drawing and try to see an image inside the scribble. Maybe you see a story or an interesting character. Try to see the potential of your doodle drawing and how many fun ideas you can pull out of it. Put a piece of tracing paper over it and try drawing the image you think you see. Render it, color it, and most of all, remember to have fun.

So you are an artist and you want to make a living. You decide that you want to start a business from home, whether its selling your art, licensing your images or freelancing. It sounds great. So you try it. After a few weeks you realized that its much harder than you expected. Many distractions prevent you from fully concentrating on your work; television, family members, phone calls, food, etc. You are so overwhelmed by all that needs to be done that you end up doing nothing at all. Eventually you freak out from all the stress and yell at the next family member you see.

In is article I have composed a list effective work tactics that will help you achieve your goals, stress-free.

You need a Game Plan
Write up a detailed plan for your business.This is the most important step of the process. Be as specific as possible. What your present situation is, where do you eventually want to be, and what are the steps you need to take to achieve your goals. Break your plan down into steps so you don't overwhelm yourself. Know that it will be a long road ahead so take small steps, make short term goals and constantly revise your plans.

Be realistic about your goals.
Don't try to pile on more than you can handle.Prioritize. Start with the more important tasks first and than if you have time, work on the rest.

treat it like a Business.
Treat it like you would any regular time-clock punching job. Set a time when you start work and a time when you end it.
Treat it Like any regular full-time job, you work for eight hours a day, get two ten minute breaks and a half hour lunch. Make it a habit to turn your TV off and keep it off while you are working.

Do not mistake playful sketching with work. Work is the time and attention you put into designing or making a product that will potentially be sold or reproduced to turn in a profit, which will in turn, provide you with enough funding to continue with your lifestyle.
Therefore, the art that you make for yourself, your friends or family for free should not be considered work and therefore, should only be done at the end of the day, after your real work is done. Creating a piece for your portfolio which you will than use to promote your business is considered work and should be perfectly acceptable, whereas a portrait you are doing of your best friend as a birthday present is not work.
