"What was your greatest challenge to success in SFI...and how did you overcome it?"
Well, to be honest, once, I was so close to give up! So close!
And than, my Sponsor helped me! She didn't give up from me :)
When I wanted to stop, she pushed me a little and I was back again.
I will never forget that and I will be always grateful for that to my Sponsor!
I hope that you have such a wonderful Sponsor too!
