Matthew 6:25-34 talks about not worrying about the things we need for this life. Because God say's for us to not worry at all. I take what the author mentions as examples, and include wives, children, and any other needs we could be concerned about for life.
The most important part of this to me is versus 33 and 34, where it says to seek 1st the Kingdom of God and His Righteousness, and all these things shall be added to you (Remembering that God's will should always be a part of whatever your seeking as part of the final outcome, being willing to accept whatever He chooses for you).
Being shy to me is no different than being outgoing or in the middle, it's probably just who you are at this point in your life and no big deal. Actively seeking God, and seeking to server Him and others will put you in contact with people automatically.
I was shy too when I first became a Christian, and I too wanted to get past my shyness, and get to know people at church, so I volunteered to be a greeter. Worked like a charm, and I even met my wife there.
My goal wasn't to find a wife, it was to honor God. This and other lessons I've learned so far, is that don't do things so God can bless you. He already knows your needs and His plans for you, and His desire is to bless you - His way.
As in Matthew 6, set out on a path that "Seeks 1st the Kingdom of God", and creates a pattern of choices for serving God and growing for your whole life because of "Eternity", and freedom from worry, believing in your heart that God loves you personally - Jer. 29:11-14, and will care for your needs way beyond what you could ever do for yourself.
God bless on your wonderful journey of honoring The Lord
