Finding something that i can be Passionate about

I'm Just floating threw life right now and am having a rough time financially, I have 5 Kids and a Great Wife, I feel so empty going threw the same routine every day. I would like Prayer that the Lord would show me a path of something that I can do to earn a living for my Family, but yet still be Passionate about I want purpose in what I do. So Please Pray that the Lord guide my path and open doors to life long opportunities to bless others.
