Would a superstar love everyone in the world that he receives so much love from everyone? Most likely not - certainly not in the beginning when he or she is struggling to make it. Maybe later in their lives when they realise that they are being showered with love from all and sundry for just being themselves.
In the beginning, though, (I feel) the difference between them and others is that they love themselves immensely and forget about everything else. And when they do that, they find the space to make themselves better.
Others find it difficult to love themselves. They put up a facade of loving others etc but it's just an escape from the incapability to love yourself. Clearly, we cannot love others if we do not love ourselves.
The starting point then to receive love is to love yourself.
