Bio mentioned this as well, but the advice to not start with a blank canvas is a very good one. Aside from using differing paper tones, it can also help to doodle on the margins to help 'ease' yourself into the page. Some people find it helpful to do abstract or even random swirls and lines (loose flowing, wide scribbles, really) to help get over the initial hesitancy/block, I happen to be one of these. I think I had an example of this waaay long ago back in my thread... ah yah
here it is.
While I haven't been practicing this lately, another good piece of advice I picked up was to promise yourself to commit to the least amount of effort everyday, which is simply picking up a pencil and drawing one line in your sketchbook. The point being, by the time you clear you schedule and mental activity to make room for the practice, you'll already be in the right place of mind to do some drawing no matter how small or little.
And the best way to keep on top of things is to get someone to keep you accountable for this. AAA's kinda dead, but posting in here's not a bad idea if you don't want to find someone irl to do it with.
Oh, but don't get discouraged if you do decide to start posting a lot here and start not getting much responses. It gets a little difficult to comment when the same user posts a lot of content in short intervals. If that happens, then requesting for a response on one specific thing will probably be better than asking for a blanket of critique. Pretty sure there's a couple people around that wouldn't mind receiving the occasional pm for short thoughts.
