Thanks for this reply, now I know not to waste any more time with you. You clearly know everything. Best of luck.
You know how I know you're full of it? Its the bullshitter's law: the amount of knowledge a person has is inversely related to how well they claim to know a topic.
Since you already know everything about motivation and achievement, there's nothing for me to discuss here with you. Everyone is weak and stupid except for you.
What's more important is finding activities that are naturally motivating and fun to do. These habits are far easier to build when they are more rewarding.
And then you naturally build discipline because the cost of missing out becomes more expensive to you.
