In a hypothetical time machine; assuming all the selves act similarly and refuse to learn from previous lessons, inevitably the individual will be trapped inside the same chamber of learning paradox, thus without any significant improvement. This will never change, unless a self at a point in time, act uniquely and triggers a revolution.
You are often irrational and born with almost zero reasoning capabilities in manipulating the present to extrapolate the future to your benefits. However, as you grow older, things will get better with more time and experience as you contemplate deeply further into the past, and therefore the future.
"The farther backward you can look, the farther forward you are likely to see." ~ ChurchillNevertheless, this trajectory is not equal for all men as some can develop rather really quickly, but others can be a bit slow. In many cases, the childish personalities are prisoned inside the body, as the soul refuses to change.
So now, you need a strategy to play this game. How do you trap your future selves to act in a set of smaller and better choice of actions? How do you frame them into playing a game to your "good" advantage? How do you manipulate their rational and irrational behaviours, which are almost perfectly known to you? The answers lie within your current self. Whenever a “good-behaved” party control your inner parliament, recognise the moment, quickly grab the opportunity and try turning the table as much as possible to your advantage.
You’ve got to think of things, that your current self is likely to be attracted to, and further manipulate these desires into a semi-permanent tug of war game, slowly developing a better self. Or perhaps try having more positive external factors, to comfortably outnumber the negative internal forces. You are indeed, playing game every single moment of your life. More often than not, when you’re awake, you have to make decision about what to do. In fact, you are more accountable to yourself when you know that your reputation is at stake, thereupon corner your senses from all possible directions and try manipulating your weaknesses into a pure awesomeness. People often said that, be hell with what others think about you, but in reality you do actually care about how they perceive yourself. Eureka!! Turn the moment into a battle between your inner selves. Use the external agents to help crushing your bad selves from the future, to make sure that they submit to your current plan, as accurately as possible.
However, always remember that your future selves have almost complete access to whatever information that you currently have now (ignoring the fact that men tend to forget things, all the time).
This situation is not unlike an excerpt that is taken from George Santayana's The Age Of Reason:
Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it. In the first stage of life the mind is frivolous and easily distracted; it misses progress by failing in consecutiveness and persistence. This is the condition of children and barbarians, in whom instinct has learned nothing from experience. In a second stage men are docile to events, plastic to new habits and suggestions, yet able to graft them on original instincts, which they thus bring to fuller satisfaction. This is the plane of manhood and true progress. Last comes a stage when retentiveness is exhausted and all that happens is at once forgotten; a vain, because unpractical, repetition of the past takes the place of plasticity and fertile re-adaptation. In a moving world re-adaptation is the price of longevity. The hard shell, far from protecting the vital principle, condemns it to die down slowly and be gradually chilled; immortality in such a case must have been secured earlier, by giving birth to a generation plastic to the contemporary world and able to retain its lessons. Thus old age is as forgetful as youth, and more incorrigible; it displays the same inattentiveness to conditions; its memory becomes self−repeating and degenerates into an instinctive reaction, like a bird's chirp.
