Random Intermittent Reward (known as Variable Ratio Reinforcement Schedule in the field of Applied Behavior Analysis) is a powerful concept from psychology. It states that the increase in motivation (through dopamine) from the anticipation of a reward is stronger when the reward is not guaranteed. You can see this effect in action with gambling, social media, mobile games (especially loot boxes), and dog training. If you're noticing themes of manipulation or addiction, that's not accidental. In the most typical and visible places that random intermittent rewards are implemented, it reinforces behaviors that are not well aligned with people's values.

It seems like a waste for something this effective to only be used against us, when it could be a huge asset for our personal growth.

I want to know if you have tried using this concept to motivate yourself to do things that are important to you. How did it go? What kind of behaviors were you trying to motivate? What kind of rewards worked or didn't?

Disclaimer: I've been using this concept for a while now to great effect, so I'm building a phone app to make it easier, more effective, and fun to use. You can go to https://tantaluspath.com to see more information and sign up to get notified when the app is available.

If you don't have motivation but you can master discipline. How will it work out in real life? Will you still be successful,happy, bla bla bla...
Is is similar to, "hard work can beat talent"? Or is it something else.

P.S Related example of these scenarios are appreciated.

Something that has always been tough for me is embracing incremental progress. I get bursts of productivity followed by time periods of inactivity. When I think about my shortcomings, they sometimes seem too large to overcome with this strategy, so I know I need incremental progress to get there. Reflecting on examples of incremental progress that I've made, they have all happened with a good amount of outside influence. For instance in sports and in school growing up, I was forced to go to practice or do homework by parents, etc.

Are there strategies for gaining motivation for big projects like getting in shape or completing a coding project--especially now that I don't have things like deadlines or authority figures forcing me to do these things? Or does it more come down to discipline?

Would love to hear everyone's thoughts!
