From experience, you possibly make too many pawn moves, or move light pieces (or the queen) twice or even more often.
It is a common error for weaker players to make moves that the opponent can defend and counterattack by developing a piece, and then you need to move the piece again.
Try to verify for each move:
- is the field you are moving to not a good and save long-term position?
- can the moved piece be easily and immediately attacked and forced to move again?
- does this move force the opponent to make a good move (developing one of his pieces)?
- did you move this piece already before?
- is it a unnecessary pawn move?
If any of this is true, it's potentially not a good move, as it loses you valuable time. Try to find another one.
Once the opening is over, these rules become less important; but don't lose tempo during the opening.
An efficient opening moves each light piece only once (4), only a small number of pawn moves (2-4), castles (1), and positions the queen (1), so after 8 to 10 moves, your rooks should be free to roam (not that that is necessarily what you should do next - but you could).
There are of course exceptions to all this. But generally, it will be very useful to keep those in mind.
