HI and welcome to the board. I've shared some ideas regarding the credit system in your post below.

Congratulations on stepping into the journey of the Nurtured Heart Approach. You will soon discover that seeing the positive will become much easier the more you practice and grow and use the tools. One of the most important things I want to share with you regarding the Approach is to breathe and it's ok to reset yourself frequently! You are Greatness in action and every recognition of greatness you share is a greatness within you! Believe it, honor it!
Please drop in as often as you need. We're here and looking forward to helping you along the way.
