Don’t move the same piece twice (at least early on). Tempo and development is very important.
Learn about openings, and pick one to use as your standard. The best ones have already been figured out, and provide a “base” that is very well protected but will also allow you to attack efficiently. There’s no reason to reinvent the wheel with them – they have been perfected over the history of the game. Playing from the same opening every time also makes for fewer possible moves to consider – so it’s easier to pick good ones. And you’ll run into the same situations over and over, so you learn what to do and what not to do in that situation in the future. You essentially have a standard plan, and have an idea of how you want to trap the king, and you just practice that in every match. So you’re following a well rehearsed plan instead of just reacting to what your opponent is doing.
