You cannot force-feed someone to success. You can only show the ladder. In the end, one has to walk on it. We want to see our loved ones and friends succeed. We go to lengths to help them out. But in the end, it all comes down to the individual.
We have to be happy with our efforts. Otherwise, we will be in pain for seeing them fail without them making an effort. Our mind throws us into a guilt trap. We have to avoid it. We are not responsible for others beyond a point.
