There are a lot of great comments here about what to do but wanted to add something a little different. Most of the advice here about what you should be doing is reasonable, but one critical thing that's missing is that most people that do the right, pro-social things, don't do it just to get what they want. When it comes to highly important decisions, sure, people strategize and ensure that the consequences are personally beneficial but for the most part, people act properly in social situations because they are socialized to instinctively care about other people's needs. People are programmed (through some combination of nature and nurture of course) to take into account the needs of others that they spend time with, whether bosses, coworkers, friends or family.

It appears to me that you're missing or perhaps blocked out some of this conditioning. The reason why people are throwing out terms like "sociopath" or "autism" here is that you do not seem to have any instinctive regard for others or even your future self in any of your stories - either you don't know how your actions would affect others or you don't care. I know a lot of people think being relieved of having to care about others makes it easy to become successful because they think they can then take advantage of others without any qualms, but this ignores motivational aspects. For most people, naked self-interest isn't motivating enough to get people to do the right things even for themselves. People that aren't motivated by something that's bigger than themselves - whatever the causes may be - usually find it difficult to put off instant self-gratification and control their emotions enough to do what it takes to become successful. To be motivated enough to overcome your habits, you may have to learn to care about other beings beyond your immediate self. This will also make it easier to instinctively do the right thing - you don't have to pretend to care, when you actually do.
