Raphael Zernoff said this quote
“ We truly help others working on ourselves. When it comes from the knowledge that the only power we have is over our own choices, we do not struggle taking responsibility for what is not ours to be responsible for. When we choose to be happy our joy works like a lighthouse. The lighthouse does never guide ships to its own light. It always leads them to the safe harbour. Yet it is their choice, whether they want to follow the light or something else. ”
