Thank you very much for writing in this question. Boredom is a major culprit in undermining our psychological well-being. I think the fact that you are noticing this lack of feeling bodes well for the opportunity to make changes. Being too bored or too anxious keeps us from engaging in our life. The lack of engagement you feel is at the core of understanding how to correct this.
However, re-engagement doesn’t just happen. You need to specifically set out to try new experiences. Sampling activities will give you a real information about what will grab your interest. The goal is not merely to move away from boredom, but to move toward something that will give you goals to pursue.
To get out of a valley you have to climb a mountain.
