What next

I was asked frequently as a little child "What do you want to be when you grow up?" Well as  the year's went by, my answers have changed.

But the question now is: How am I going to work for God?  How am I going to further His work?

Theses are some questions that are in my mind everyday. It's almost school time again,....and this year, is my last.Then "what next? "
Right now I'm thinking to be a Medical Missionary aslo studying:
Literature Evangelism
Music
Media
Culinary Arts
Writing
and Public Speaking.

But there's another question in my mind, does the Lord want me to study those things? 
My prayer is "Lord show me my calling, show me what you want me to do for you. " 
Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few; Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.
Matthew 9:37-38

The laborers are few, and I'm going to be one of the few. The harvest is plenteous,... there's no time to waste. 

The harvest is past, the summer is ended and we are not saved. Jeremiah 8:20

I WANT TO BE SAVED!
