If you ever get a chance to meet your younger self. What would be the advice you want to give?

As we are living in the fast paced world, my advice would be to appreciate life, live every moment & learn to embrace all the good things around. 
In case you're not feeling happy it's okay, because happiness isn't a destination but a long life journey. The process might be slow but the results will be worth the wait. 
Look for joy around you and all these chakras around help us to improve our well being and enable us to live life as our best.

And to live at best we all need a companion in life. Our fallback, our go to person- whom we can trust. A positive person next to us will impact and cherish our life beautifully. So choose your fallback wisely.
