What constitutes success and failure?
The outcomes of failure and success and how some people choose to use them to their advantage
Failure almost always entails one of two things, and often a combination of the two: Demotivation and motivation. Demotivation comes from that feeling of defeit, and that feeling that you might never actually accomplish the task that you have set for yourself, or even worse, that it might no longer be worth striving for. Those who endure and keep striving forward are those who succeed in contrast to others that go through similiar circumstances but give in to defeit. For that reason, one must keep a positive outlook on his path so that the obstacles which he/she has encountered can be considered as lessons instead of downfalls.
What is normally considered a success or a failure is often ambiguous
Success and failure are both quite subjective. They can depend on several factors including the goal(s) that you have set and how you choose to approach them. If your goal is to build a million dollar organization by the age of 30 and you have come really close but have not been able to achieve that, then you might consider yourself as a failure with regards to that specific goal. Nonetheless, someone in the exact same situation with the exact same goal in mind might consider his progress in approaching that goal as a big trait of success, even if he/she has not actually reached his/her target just yet.
The break-even points in reaching your goal(s)
There are certain break-even points when it comes to goals which also are not always clear. You might have reached your desired outcome(s) in the exact period of time which you had set for yourself to be able to reach it in. However, you might have exhausted more resourcess than what you should have while achieving that specific goal, whether those resource shortages be social, psychological, monetary, physical or otherwise...
