“What God wants you to do is to believe in the one he sent.” (John 6.29 GNB)

And by "believe", we need to act the belief consistent to what Jesus taught.

Often times, the answer to the question "what is God's will for me" can be found in front of us. If we are honest in seeking his will.

What did Jesus teach?
What would Jesus do?
What would bless others?
What would give glory to God?
What would be good for the work of the kingdom of God?

That would be God's will.
