Giving someone a helping hand is something you should do because it's the right thing to do: not because you want people to see you as selfless. Find another way to promote yourself, don't get other people involved in it. There's nothing wrong with trying to make the world see you in a certain light, but there's no need to create a big drama around it. Your best advertisement is to just be yourself. Putting on an act that you want people to see is just exhausting.
