Just want to mention that besides saying tehillim, we should also learn and practice shemiras halashon because that will help our prayers be more effective. When our mouth is impure, our prayers are blocked, but guarding our speech helps our prayers to ascend.
The more we learn, the more we know what to say and what not to say and then all we need is to just keep at it. And we should try to be careful about listening also, unless it's absolutely neccessary.
Plus, knowing the rules of toeles/constructive purpose, is very important when we have to say something and are trying to stay within the guidelines.
Hopefully with our efforts, our prayers will make a tremendous impact.
