Real Answer #1:
There is a head side of this question and heart side. Here is the head side.
In Psalm 16, God uses the word pleasure. He says that we would find eternal pleasures. Not just the passing fancies, or “Wow’s” of life. But eternal, lasting forever pleasures. The ones that do not fade or spoil.
You have made known to me the path of life; you will fill me with joy in your presence, with eternal pleasures at your right hand.
Isn’t that an odd choice of words, unless, unless. . . . Unless we are made in his image, so the whole notion or idea of pleasure comes from Him anyway.
So in a heart way, try to remember what you said you would do at age 10, age 15, age 20. Somewhere in there are desires and thoughts and dreams you had before the world started knocking you around and down. Write them down and pray over them and let God sort, reveal and refine.
Still stuck? Try doing a vision board, a collage of pictures torn from magazines, that express aches, wants, “wish I could” ideas. And let the Lord surprise you over time with more revelation of who you are and what he had in mind for you.
