Danish Gambit declined, what next?

This is indeed a tough chess match after the opponent declined my Danish Gambit’s pawn sacrifices. Now what? My entire game plan needs to change after the Danish Gambit Declined. There are fast exchange of pieces going on on the chess board and he seems to keep up the pressure on me and there is a moment when I think he might wins the game because he is in the total control situation. However I manage to set up a little trap and finally win against my better skill opponent.

I start the game with Danish Gambit but switch the entire game plan after my opponent declined my pawns offer.
