I think the big one for me is to break all of the negative mental habits I have whenever I draw. (Stuff like hating everything I draw, expecting something good on the first try/giving up too quickly, not learning from mistakes and putting myself off whenever I get the chance to sit down and actually have time to draw, among other mentality stuff like those.)
On a more technical side, I don't really have an end-goal, so I just set smaller goals as I go along. For example, my current goal is understanding human anatomy to a more accurate level.
Though if I could single out an end goal, I kinda want to release an artbook of some sort!
