I\'ll take a stab at this, although I\'m not sure I\'ll be able to stick to 10.
1. Good lighting first and foremost - if you can\'t see properly you can\'t paint well. And eyestrain will only get worse the older you get if you\'re painting under light that\'s not bright enough.
2. Get into the right mindset before you start to paint. In general, slow down - if you\'re feeling impatient it might not be the best time to work on something you want finished to a high standard.
3. Adopt a comfortable posture to paint - if you get up after a painting session and your shoulder or back is sore you\'re probably doing something wrong. But even with this get up and walk around regularly, do some stretches, anything like that; nothing like regularly sitting for four hours in one position to screw up yer back!
4. Buy, make or find some tool to comfortably hold figures for a long time. A larger-diameter handle is a good idea.
5. Don\'t lick your brushes! Individual colours or the paint generally could be toxic to you. This is especially important if you have any existing allergies or sensitivities.
6. Use a double-bath system for rinsing; a big jar for the first one, the second can be smaller. You rinse out the paint in the first and then rinse out the dirty water with the second, which helps keep brushes a lot cleaner. The second jar will also stay very clean for a long time so you stand much less chance of polluting a light colour if you use tap water for thinning. 6b. A small amount of dishwashing liquid in your rinsing water also helps keep them clean but remember not to add any if you\'re painting in a way that needs the paint to have surface tension.
7. Wash your brushes periodically if they need it, but remember that prevention is better than cure. Quite frankly a few brush-cleaning soaps aren\'t great shakes; common hand soap can do the job as well or better than some.
8. Good brushes are worth it. While synthetics have their place there are things you can achieve with a needle-sharp Kolinsky you can\'t do with another brush as easily, or at all.
9. If you\'re using natural-hair brushes why not try conditioning them every now and then, especially after washing. It won\'t hurt the bristles and it could help maintain them in good shape for longer. You can leave conditioner in a brush when not in use and just rinse it out in your jar before you paint if you like.
10. Use the largest brush you can for any job. Generally speaking painting all the time with brushes that are too small is both slower and less efficient and has a tendency to make the paintjob look fussy.
11. Read everything you can about painting, including books for artists. Even books about a different medium might have something you\'ll find useful.
12. Don\'t be afraid to try new things. Trying something for yourself is often the only way to know for sure what it\'s really like - this applies to different paints, brushes and techniques.
Remember if you always do what you\'ve always done you stand a good chance of always getting what you\'ve always gotten; which is fine, if you think your standard can\'t go up.
13. If you go looking for other people\'s colour recipes as the first port of call it can hold your development back; we often learn more from screwing up than from the things that go right first time! Experimentation can lead to insights you\'ll miss completely using mixes some other guy used.
14. Paint the way you want. The only requirement to paint like the current vogue or using the technique of the moment is if you\'re painting commercially and that\'s what the customer wants or the market is buying.
15. Be wary of rules when it comes to colour and mixing; most of them are just generalities (some are just wrong!) and might not apply to the specific colours you\'re using because paints mix the way they do because of their pigments, not just because of \'their colour\'. For example some reds do highlight just fine using only white, similarly nearly any dark colour will shade with black perfectly well and some lighter ones work well with it too. The only way to know for yourself is to try mixes and see.
16. Practice! This may be THE important rule. You\'ll tend to get a lot better, and faster, actually painting than you will reading about painting.
