When trying to improve the intrinsic (not materialistic) quality of our lives, we tend to usually focus on our problem areas and come up with strategies to address them. While this is crucial for us to evolve as better people day over day, they can sometimes make us too singularly focused.
What helps to have alongside such serious goals is to seek out people and experiences that invoke curiosity, excitement and just pure joy.
Going to your favorite concert. Exploring a new city. Learning a new hobby. Having a party.
These experiences can infuse light to permeate darkness in a way that nothing else can.
