God made us for his pleasure.
We recognize we are corrupt, so we accept Christ, and we become more like Christ.
1. Learn about God, glorify God, and become like him.
2. Evangelize
3. Make a good life for yourself and others.
Why else are we here? and what are we to do now?
The Reformed have logically deduced that there are 'two wills of God' as the Bible uses the phrase "will of God". One is the command, or revealed will. The other is his plan, or hidden will. While you can often reject or 'step outside of' his command, there is nothing you can do to change his plan. I personally don't care for the wording, "Hidden will", since there is quite a lot we can know from Scripture about his plan.
We know from Scripture something of why he made us, and of what he is doing with us here. We certainly are to do your list of 3 categories above, and while your question (and your list) implies our works and ambitions, attitudes and obediences, it needs to be understood that these cannot be accomplished by our will alone, but by God's will, and by that I mean his plan (which implies not so much our work, but HIS (Not at all meaning we don't work)). Apart from Him we can do nothing (see John 15:5).
He is working ON us, the Redeemed, making us suitable for each one's particular place in his Dwelling Place —there is almost no end to references to this, passages alluding in one way or another to it— and this, we know, WILL BE ACCOMPLISHED, with or without our cooperation. Yet, IN HIM, we must obey, and walk in faith. Trying to figure out what our job is, and how to do it,
as if our part is separate from his, is useless. We do it
because he is doing it.
