Having a me-first attitude is not selfish at all. In my opinion, self-love is the most important love out there.
The concept behind "me first" is that if I am not at my best mentally, physically, spiritually, and emotionally, it's almost impossible for me to perform at the best level and show up as the highest version of myself in the lives of others.
This necklace is just a reminder that whatever happens in life I need to put me first before anything and anyone. Take a break, show yourself some extra love, and put yourself first so that everything you desire from the universe could fall right into your hands at ease. The opposite side is a hammered texture, so where it however you'd like!
