3. not spreading creep. At all.
4. getting badly supply blocked more than once in a game

9. Not having ONE army (unless you have a plan that needs it split)

17. Failing to realize when the other guy loses his army, he has nothing left and is probably only just starting production (see 12, see 16)

34. Leaving tanks that can siege up, sit un-sieged
35. Going to three bases without the ability to defend an attack on one
36. Starting work on an expo without any static or moving defense
37. (as T) flying a command center to an island without first loading it with SCVs
38. Not checking you have 3 on gas especially after a fight at the mineral line
39. Using orbital energy to increase supply or do scans that could be scouted by a unit
40. Trying the same smooth move more than once
41. (as T) Switching cloak on and off, turning it on uses a lot of energy!
42. Having no clue how to use ghosts, ravens, and other odd units
43. When attacking, not being patient and attacking a less established expansion first
44. Forgetting to do tech upgrades

47. When flush with minerals, not building out future supply
48. Screwing up your hot key groups, and not fixing it
49. Wasting time just watching the outcome of a battle (time passes really quickly!)
50. Wasting time watching a harass (a drop or whatever)
51. When in the enemy base, having no clear idea what buildings/pylons to kill as a priority (shooting at everything)

61. (as T) not being aware that there is a P observer over your army, or base, or both
edit: and a free one, maybe the biggest
62. rarely looking at the mini map and not clicking in it
an after thought:
63. Rallying to your battle point, producing while moving, and forgetting you have a blocked ramp (coming home in tatters to see all the units that couldn't get out). Doh!
