Getting new habits to stick

I was reading Engineer Life: Set Up Habit Changes So It’s Hard to Fail,  which advocates applying reinforcement or "feedback" from all angles: with positive and negative reinforcement to the desired behaviour or habit  and alternative undesired behaviours - old habits or not bothering with the new habit - until repetition makes the new habit into a well-worn path. 

Here are the mentioned sources of reinforcement and the directions of reinforcement stated with parallel constructions - because it looks neat to see the same thing from four different perspectives. 

Some sources of reinforcement

• Social reinforcement: via friends, clubs, classes, forums, coaching. Positive from encouragement and congratulations, negative from discouragement and chastisement.
• Self-reinforcement: positive from congratulating yourself and celebrating small successes.  Negative... usually works against you.
• Convenience: positive from making the behaviour convenient, negative from making it inconvenient. For example, being near to a gym vs far away.
• Satisfaction: positive from making the behaviour more pleasant, negative from making it more unpleasant.  Get a bad screen to reduce time spent on the computer?

Make it easy to carry out the new behaviour

Strengthen positive reinforcements for the new behaviour by adding positive social feedback, positive self-feedback, and making it more pleasant and more convenient.

Weaken negative reinforcements for the new behaviour by removing negative social feedback, negative self-feedback, and making it less unpleasant and less inconvenient.

Make it difficult not to carry out the new behaviour

Weaken positive reinforcements for alternate behaviours by removing positive social and self-feedback, and making them less pleasant and less convenient.

Strengthen negative reinforcements for alternate behaviours by adding adding negative social and self-feedback, and making them more unpleasant and more inconvenient.
