First, realize, that you're inherently time-locked: the current self is the only one on which you have some amount of control
Actually, I have managed to cause short-term changes in productivity to my future self but they tend to slowly wear off. This makes me optimistic that there are self-sustaining solutions.
What were these changes? What was the experience of them wearing off like?
I don't like doing much work. I would however, like my future self to do work so that my far future self will have better opportunities.
To clarify, I want these things for each specified self:
The problem is, I expect that my future self will feel the same way and also want immediate gratification. What can I do now to achieve all 3 of those goals? How can I manipulate my future self into doing more work without having to do much work right now?
