These adjectives apply to people who perform actions marked by insufficient care or attention or to the actions themselves. Careless often implies negligence or casual indifference: "It is natural for careless writers to run into faults they never think of" (George Berkeley).
Heedless can suggest willful or reckless disregard: "She ... watched the top of the hill for someone drunk or heedless coming over it in part of her lane" (Andre Dubus).
Thoughtless applies to actions taken without due consideration; it frequently implies lack of concern for others: "a thoughtless remark about the war that will worry an already worried child" (Kristin Henderson).
Inadvertent implies unintentional lack of care or attention: "For the deterrence theorists, the greatest worry was inadvertent war, a cataclysm that might follow from misperception" (Eliot A. Cohen).

If you are careful, you do something with a lot of attention.
