To live your life fully and ”go out and shine in the world” is a good mental image I believe. Show the world who you are and what your are about, and do it with excellence! To shine in the world can be to show your beautiful inside by supporting and helping, encouraging and friendly pushing, those around you. Always with others best in mind. And you will see that by putting others in the spotlight, the light will shine back at you. In a good way.
Wish you all the best. Take Care. Namaste.
