Explanation: Your gift is rather self exlainig. But to clear things up, you have been given a power that makes you extremly strong. This is of course speaking in pyshical terms. When doing good deeds the power could be used as helping people in e.g. fights or those under a fallen building etc. For bad purposes the power could simply kill/beat anyone until the gifted gets his way.
You are however as a person on the good side. You are the leader type and have a tendancy to look at the whole picture rather than details. That could make you come off as inconsiderate, but that's far from the truth. You can be impulsive and aggressive but you mean no harm with it. Sometimes it can even save you. If you were to be in a group with others who have super powers you would be focusing more on them and the situation rather than yourself. So to even it out, you can be egotistical at times, but it's because you ignore your needs every once in a while. You are responsible and brave but could still be seen as reckless.
Negative aspects: Since you focus on the team/family/group of friends you could start thinking that they don't care about you since they don't seem to look after you the way you do to them. Also you could intentionally endanger yourself (even in everyday life) when doing descicions without thinking it through that much. But a leader with more sense of responsibility does not however come off as reckless, but logical.
