Success is a habit, sure. But to pick up this habit, you have to have the right mindset. You can force things and hang on to your old mindset while adopting new habits, but these eventually wear off. 
Successful people do certain things consistently, and that's why they achieve a higher degree of success than most other people. But there's more to it than that. It's not just a matter of doing certain things over and over again given certain circumstances.
When you adopt these success habits without changing your mindset, you eventually end up where you began. How come? You built your new habits
on a faulty mental foundation.
