Love yourself fully with all your unique quirks, specialness and flaws and then you can truly love others. Share your love, keep your heart open, learn to trust and share your light.
Those who see and connect with your light will appreciate it and be so grateful for it. Catch yourself when you are being judgmental and question why to understand yourself better rather than focusing on the other (it is way easier to focus on others).
Do the self work to grow and heal, it is life-long journey but so worthwhile for you and all those around you. Find what brings you peace and joy and relish in that as much as possible. This is the journey of life.
