What More Can I do to Repent?
Brainstorming is a great way to come up with new ideas.
The key behind brainstorming is to write everything down. It is then that your brain knows that you are serious, and it will keep bringing up new ideas.
If you wish to do more for God by repenting, consider writing down a question like "What more can I do to repent?" in the middle of a bit of paper.
Keep writing every idea down, and don't stop until you feel it's all on paper. It may take a few minutes.
You might end up with something like this.
This will give you a whole new level of insight as to what goes on inside your brain.
This kind of brainstorming is essentially the equivalent of having a good hard look at yourself in the mirror.
Now that you have new ideas you can start thinking about how you can make them happen. For example, you can take "pray more often", and turn it into "pray when I wake up, in the afternoon, and in the evening, etc.
Your brain is like a really smart computer. You just need to ask it the right questions.
