Have trouble getting up for morning runs? Lay out your running gear on the bedroom floor the night before. Then move your alarm clock across the room, so you'll have to get out of bed to turn it off.

Your 'base layer' shirt should be synthetic (to wick away perspiration), but just as important: It should fit snugly. If there's air space between you and your first layer, sweat will stay on your skin, cold air will find its way in and you'll get chilled in a hurry.
