Definitely procrastination it's one great enemy of success and and knowing fully it affects alot one need to take a bold step in running pass this, I like the points you that you stated here they are all major aspect that one need to avoid inorder to become rich or successful, and in the quest of riches one aspect that really matters is knowing the circles of friends you keep cause it validates your success and if I would want to add to this I think consistency in anything you tend to do to become successful should be taken seriously.
