Every problem has a source. If you spot the Truth of a problem, it (the problem) ceases to exist. As Jesus said, know the truth and the truth will set you free.
This is another way of saying, take 100% (or perfect) responsibility for the problem. Even if others seem to be the "cause," if you take 100% responsibility for their actions, then you are taking the altruistic viewpoint that is one of perfect love.
The really cool thing is, if you think you spotted the source of a problem and the problem continues to persist, then you have NOT found the Truth of the problem. Keep digging. Or ask God for help spotting the source. Allow the answer to come to you. If you do it correctly, it is entirely effortless.
This works for problems of any nature, including curses, bad luck, etc.
