The list @imbacon has often posted has a lot of useful tips.
Opening Principles:
1. Control the center squares – d4-e4-d5-e5
2. Develop your minor pieces toward the center – piece activity is the key
3. Castle
4. Connect your rooks

Pre Move Checklist:
1. Make sure all your pieces are safe.
2. Look for forcing move: 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?"
About a week ago I started to practice playing chess. Since I was a kid (now I'm 20 years old) I used to play sometimes but I've never taken it as a subject of study. I have been reading some books, learning openings and being interested in the subject, I feel that I have advanced a bit in the game, but I still have some "knots" in my head to solve.
Since in this application I have a very low elo, although I do not give interest to that, because sometimes because of work I have to abandon games, or sometimes I make stupid mistakes and abandonment, also when I win the game intellectually but the other player is still playing with only his king and does not give up, I also leave to not waste time.
My question is: Is there an opening that puts me ahead against very little elo rivals like the ones I usually face?
What do you recommend that I start paying attention to get a considerable advantage theoretically speaking?
I feel that in the elo that I am, it makes me a little easy already, that's why the question comes. I hope to move forward and I will continue reading and practicing, thank you!

This is my last game. Most of the game I had an advantage against the opponent, I had two or three mistakes that cost me enough the game, and then what always makes it difficult is in the finalization of the game once I am in advantage. I would appreciate any recommendations and advice.
