i Wanna improve :)

Good

It's easy, really, just improve and that's it.

Win games

Hire a coach/tutor.

Improve fast in chess is a bit hard, u need to have time and energy to have a long plan if improvement.It is not easy but analyzing your games and watching top games u can get improve in long time.No do my error:no waste too much time on opening, it is better to study middlegames and endgames.For example endgames with rook and pawn have different theorical endgames.Then learn to draw with a rook vs rook plus bishop.Then win with bishop plus knight vs lonely king.

lol

Play long time controls with a real board and pieces.  Don't touch any piece unless you have ABSOLUTELY made the decision to make a move with it.  Ask yourself - if I touch this piece, where is the blunder? Review your games, especially your losses, and find the exact moves where you went wrong.  Be especially honest here.  Focus as a beginner on opening principles and tactics, tactics, tactics.  Don't worry about memorizing any lines yet. Just play more to become familiar with the openings you do face.  

Play a lot of blitz, should help you

The way to improve quickly in chess is by employing patience

The basics of each phase of the game

Opening:

Follow the Opening principles:

1.      Control the center squares – d4-e4-d5-e5

2.      Develop your minor pieces toward the center – piece activity is the key

Ø  Complete your development before moving a piece twice or starting an attack.

Ø  Move pieces not pawns.

3.      Castle

4.      Connect your rooks

Ø    By move 12, you should have connected your Rooks, or be about to do so.

Middle game:

When you have completed the Opening Principles, you are now at the middle game.  Now you need to formulate a middle game plan.  The middle game is a very complicated part of a chess game.  A simple way to develop a middle game plan is to perform the following steps.

1.      Scan your opponents 5^th, and 6^th ranks (3^rd, and 4^th if your black)

2.      Look for weak pawns, and or weak squares.

Ø  Weak pawns and squares are Pawns, and squares that cannot be defended by another Pawn.

Ø  Knights are excellent pieces on weak squares.

Ø  When deciding on weak squares, and weak Pawns to attack, the closer to the center the better

End game:

Start with the basics:

1.      Learn basic mates – KQ vs. K, KR vs. K, KRR vs. K

2.      Learn Opposition, and Key Squares

3.      Learn basic King and Pawn endings

Pre Move Checklist

1. Make sure all your pieces are safe.

2. Look for forcing moves: Checks, captures, threats. You want to look at ALL forcing moves (even the bad ones) this will force you look at, and see the entire board.

3. If there are no forcing moves, you then want to remove any of your opponent’s pieces from your side of the board.

4. If your opponent doesn’t have any of his pieces on your side of the board, then you want to improve the position of your least active piece.

5. After each move by your opponent, ask yourself: "What is my opponent trying to do?"

Sorry...you supplied no guidelines of what youre looking for, except "I want to improve faster"

Get a good coach. That will skyrocket your rating, really.

The ideas expressed in a Rubinstein or Capablanca game are generally easier to understand. They are usually carried out to their logical end, often in a memorable way, ...

In today's chess, the defense is much better. That may sound good. But it means that the defender's counterplay will muddy the waters and dilute the instructional value of the game.

For this reason the games of Rubinstein, Capablanca, Morphy, Siegbert Tarrasch, Harry Pillsbury and Paul Keres are strongly recommended - as well as those of more recent players who have a somewhat classical style, like Fischer, Karpov, Viswanathan Anand and Michael Adams. ..." - GM Andrew Soltis (2010)

You are not going to get useful answers to this here. Any useful answer would be dozens of pages long and include many illustrative games and positions. If your question is a serious one then you need to study one or more of the excellent books on these subjects, such as Sokolov's "Winning Chess Middlegames" and to play over lots of well annotated master and GM Games.

A weak square, or weak pawn is a square, or pawn that cannot be protected by another pawn.  

If you expect to be spoon fed by other members of chess.com you are not going to get very far.  

If you mean what you said in the title of this thread you will get a copy of the book I recommended, or something similar, and you will study it.
