Change of Behavior in New Body

When and if I take the next body, how will it be in regard to my lifestyle and behavior?

Do I have an undesirable behavior which I wish to abandon in the body, but which is so strong that it persists even though I wish to shed it? Can I hope that I will get rid of it in a new body because in that body, such a behavior will not be as developed?

What can I do to assure that when I take the next body, my undesirable habit will not manifest? Consider a simple habit like drinking coffee. Some of us cannot shed that habit but we say to ourselves that it is not a bad habit, that it is good in comparison to a cocaine, heroin or alcohol addiction. The truth is that such a simple habit has us snowed under, so that we cannot resist it. We keep on with it come what may.

But is there a way to set my destiny so that in my next life I can shed the undesirable habit?

Can I quit indulging myself about being all I can be, and being only my better self, while in fact I breach that daily and blatantly and am stymied by more than one undesirable trait?

Would there be a time in the development of my next body when I could set the stage to change so that as soon as an old undesirable habit from the previous life, tries to reassert itself, I can instinctually turn away from it and substitute a desirable behavior?

When in that life would that time be? At what age in that body would this happen? Would I have the required objectivity to resist it?
