To get great success, start with small steps
Remember, when you were a kid and your father trained you How to walk. You have learned walking on the ground in 1-2 years, and you failed many times but you never thought that time and you never regretted your failures. they why today? because now you are older. When you learn more you are more afraid, because your Conscious mind is active now. You have voluntary control over your body and mind. That is holding your back.
