My biggest challenge/ obstacle to succeeding with SFI is myself. I was told by my spouse that I am wasting my time with SFI.
Truth be told, when the PSA and CSA, quit or never gets started, I do get despondend and I feel like giving up.
However, I am adamant to persist, and, to learn to grow personally and to succeed. Then, to help others grow personally.
I carefully and diligently read through the SFI training and other resources. And it really helps not to reinvent the wheel, but to stick to the script and keep things simple.
