Based on metacognition theories we present a construct of metacognitive self (MCS) as self-awareness of biases. Contrary to counterintuitive idea metacognitive self fosters self-regulation in the area of goal's attainment. Study 1 (N = 118) showed that high metacognitive self individuals created more clear mental picture of their plans than low metacognitive self counter partners. Moreover participants high in metacognitive self undertook more actions to fulfill their goals then low MCS colleagues. Study 2 (N = 201) revealed that high metacognitive self individuals strive for autonomy and they work much better to attain their goals in the no load settings, while low metacognitive students work much better under supervision.

Two studies test the hypothesis of conserving resources while performing depleting physical tasks and the modifying role of metacognitive self (MCS). A total of 216 undergraduate students performed two types of physical tasks (a body support on forearms-the first experiment; and a cold water test-the second experiment) in anticipation vs. no anticipation of the future task conditions. Among individuals with high-MCS much weaker persistence could be observed than among those with low-MCS. These results support theories of adaptive goal disengagement suggesting that how individuals apply their resources may stem from other reasons than ego depletion.
