I believe two of the most important contributions in our lives is faith in God and faith in ourselves. We have both ingredients than we can do anything we want.
God says that we have faith as small as a mustard seed we can move mountains. Faith can make us do the impossible as much as the possible. Do you have that faith in God and you? If so you can and will do a lot.
Others can encourage you but you have to take the first steps toward faith. I know you can do it.
