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!
