You wont improve if you keep playing this way.
Well, the ability to see the benefit of inisiative/momentum (e.g. in a gambit) is a skill, a positional knowledge. You will learn many things such as the situation where your opponent will "give back" the material advantage for a better position or initiative. You will also learn the skill to find out whether you are superior than your opponent in one skill aspect of the game such as playing the gambit. You probably can't learn these but from actually doing it.
You are expected to make mistakes. Even stronger players than you are make unsound sacrifices. And that's one of the point. Just learn to be better at doing it (there are many that you need to master still).
Later when your rating has raised, say to a master level, you don't have to do this "stupid" strategy again. But you will still benefit from the skill. There will be moments where your only chance to win is by being good in sacrificing material like this.
Hey all, hoping to get some advice in my game. I'm still a novice player but my goal is to get tournament ready by the end of the year.
