Judging from these two games, you are not aware of the chess fundamentals.

On the first one you drop a whole rook for nothing right in the opening, while in the second a pawn, and despite your opponent's very poor play, you make some very bad blunders. The final position is winning for you, but this is not the point: If you want to improve, play games at a slower time control, and try avoiding unforced blunders.
