Here's my 2 cents on how to get better as a player:
1. Do chess tempo (30 minutes a day). Set the board up and don't make any moves; treat it like a real tournament game
2. Use ChessBase and look at any holes in your opening repertoire
3. Analyze some new openings and strategize which openings to use against which type of player. You don't want your opponents to easily out-prepare you
4. During a tournament, don't focus on winning or losing; instead, focus on trying your best and playing the best moves that come to your mind. If you make a mistake, treat it as a learning experience and reflect on why you miscalculated or misevaluated.
