The moment you decide to ask a friend for an introduction that is when. See the key is that you, in this case I, was willing to strengthen a relationship by asking for some help. See there is something to be said for being willing to go out on a limb and ask for some help.
Sometimes you win just by asking.
Now what about the other side, the brush off or lack of interest from the other party. I give it a big aw well and move on. See part of being willing to ask is being willing to get turned down. Remember just because most of the world does not have the senses to see, hear or feel an opportunity doesn’t mean one does not exist.
You need to be open to opportunities for them to find you.
Just another day. Keep moving forward.
