I believe you have a strange notion of what it means for a man to have “potential.” Your problem is you see wasted “potential” and try to save it. Men with potential are those that that have taken or are taking the right steps toward success which they have not yet achieved. Sometimes success can be elusive and doing all the right things provides no guarantees, but it does significantly improve the chances. What you apparently are attracted to, however, are not men with potential but men who have squandered potential by engaging in self-destructive behavior. You think you can save them and by doing so recover the potential that’s been lost. That’s your mistake. It’s a matter of vernacular but your advice should not be to avoid men with potential, but to avoid men engaging in self-destructive behavior regardless of how talented they may otherwise be.
