God wants us to prosper. He has promised to teach us how, but we are not promised that we will prosper when we are out of the Lord's will. We must live in God's will and walk in God's way if we want God to teach us to prosper.
God knows what we can do best and He knows where we can best serve HIM. We are not to lean on our own understanding (Proverbs 3:5). We are to let God lead us. When we are in the place of HIs leading and in the occupation of HIS choosing. He has promised that He will teach us how to prosper. Many who have failed time after time have found success when they learned to let God lead them.
I know with my piano--it is through God that I have been able to now play during congregational singing. Not my will but HIS. My fears would still have me playing only when no one sang; but now I can play about 20 different hymns with people singing. To God be the glory for that because HE was in it.
Will you prosper or fail? It all depends on who is leading you

Hugs Prayers and God bless
