Mary DeMuth's biography on Facebook begins, “If you met Mary today, her joy would confuse you.” I love that. After all that Mary has been through, the fact that she is known by her joy (not surprising if you read even one article she has written) is a testimony to the healing power of Christ. His love shines through her like light through a stained glass window.
There is no perfect time, condition, or situation to pursue your dream. Conversely, if you aren't making progress, it isn't because of external circumstances. Yes, these can put road blocks in your way. But if your dream is something you intend to do, no matter what, you will find a way around them.
