'Never move a Pawn and you will never lose a game!' You'll never win either, because it's impossible to develop all of your pieces without moving at least two Pawns in the opening.
Pawn moves should always be made sparingly. They are the only pieces with a limited number of moves : six moves to go from the 2nd rank to the 8th, five moves if they advance two squares on the first move. Their advance is always a double-edged sword : at the same time they create additional space for their own pieces to maneuver, they leave behind weaknesses that the opponent's pieces can exploit.
Pawn moves in the opening should be made even more sparingly. They should have two purposes : (1) open a line for another piece, and (2) establish a foothold in the center. A Pawn move which does both is a great move. A Pawn move which does one is a reasonable move. A Pawn move which does neither is a bad move, a waste of a move which would have been better used to develop a piece.
If White had a free hand, the best first and second moves would be 1.e4 and 2.d4 (or vice versa). Black can only dream about playing 1...e5 and 2...d5, because White has two moves to prevent that from happening.
The objectives should be clear. Restrict your opening Pawn moves to center Pawns and advance them two squares on the first move. If you can't accomplish this, be sure that you have a very good reason for making other Pawn moves.
