Commitment can be summed up very easily: be willing to be successful no matter what. In other words, one has the mindset that he or she is going to do whatever it takes to make the situation successful. Failure is not an option. All action is taken with the intention of working towards the desired outcome. There is no maybe. Certainty is ever present in the mind.
This is a stark difference from how people live their lives. Most are experts at offering up excuses. They have a host of alibis ready to present even before they engage in the activity. Of course, nothing is ever their fault. Passing the blame is a weekness.
To succeed in BDSM, as other areas, it takes commitment. My mindset is that my relationship is going to work out long term. I am not willing to allow the challenges of life to sabotage what I am developing. Fear is something that is present within everyone and, left unchecked, can overtake a situation completely. Commitment is something that enables one to overcome this barrier.
Blind faith or senseless optimism is not a valid approach. However, when one is aware of the situation after doing the proper research or diligence, it is helpful to have the committed outlook. Success and failure both start in the mind. Those are willing to do whatever it takes to make a BDSM relationship(s) successful are apt to do just that. This is a major contrast to the one who is willing to sever things as soon as something difficult comes up. Many of the reasons for ending relationships can be overcome with commitment. It is a tool that few consider but is something that can make all the difference. Consider it.
