Thanks Frankenstone on contributing one of the best comments posted on this site. The post is thought provoking and inviting a lot of attention.
I would like to rearrange the success factors as:
1- Clear vision of s successful person
2- Daily successful small actions to achieve the vision
3- Perseverance in action
4- Deep Feelings of thankfulness (It can give permanence to success).
Talents may be developed and opportunities may be created. Common sense and intelligence have some role to play as mentally retarded people can't do things correctly.
