The most common difference between success and failure?

Having a System.
Those who fail to plan, plan to fail
and
a bad (or no) system will defeat a good person
100% of the time.
Plan the work, work the plan.
Requires the simple methodology
of being self-disciplined.
Which is one reason why emotionally intelligent people will vastly
outperform people who make decisions on emotion.
For every one of us, success involves
making the shift from doing things to feel good,
to doing thing that are good.
Success more likely won't feel good while you are doing it.
In fact, you will probably not like following a logic path at all.
Those who can manage their emotional responses (child states)
to act like a logical adult, will achieve success.
Those who give in to their child-like impulses, won't.
Success therefore, comes down to our emotional
self-regulation and our behavioral
self-management.
