The person who keeps blaming others for where they are in life, will never be where they could be.
Sure, there are forces outside of our control that have worked (and perhaps still work) against us, but as these forces are outside of our control, any energy spend ruminating about this is a waste of energy.
An obsessive focus on the obstacle only demotivates us, taking away our focus from the things that really matter: the things that are under our control.
Obstacles don’t have to be a full stop.
Often, they operate as a filter, separating the strong-willed from the rest of us. Complaining is unlikely to move the obstacle. Instead, time is better spend finding a way around, in order to achieve your goal despite the challenges presented (there’s almost always a way).
Only the person who assumes full responsibility over their situation, will be in maximum control as to where they’ll go next.
