Creating Passionate Users: Create an intention calendar
It’s also the case that “You are what you think.” Every single thought in our heads is created by nerve impulses that travel between neurons. These impulses travel from one neuron to the next by being transmitted across the synaptic gap between neurons. The neurotransmitters in that gap make this happen. Every time a nerve fires, and passes along a nerve impulse, you are creating a neural pathway for a thought and each time you think that thought, the neural pathway gets
stronger.
As you’re learning something new, you’re forging new neural pathways. That’s why learning something new sometimes feels hard, especially if what you’re trying to learn is something your brain thinks is not important. But, once you’ve convinced your brain it is important and, damnit, you’re going to learn it, then a neural pathway is created for that thought. If you practice that thought, it will become easier. If you practice it enough, it becomes habit.
This can work against us. It means that bad habits are hard to break. It means that thinking negative thoughts is bad for your brain.
