First of all, you have to remember what Winston Churchill said on this subject:
“Success is not final; failure is not fatal: It is the courage to continue that counts.”

When it comes to success and failure, there is a fairly simple thought pattern that more than 95% of people have. It is symbolized by this illustration:
The remaining 4% understand that failure is part of the road to success and must be integrated into an iterative process:
These people will find it difficult to have lasting success, however.
Why is that?
Simply because they think that once they get to the top, they'll be out of the woods and everything will be easy. But that's not how it works.
The number one rule of success is that you must always challenge yourself in life.
Nothing is final.
Once you are successful, things will always be tough afterwards. So you will have to work harder, just as you did before.
The mentality you need to have if you want to be successful and sustainable is this:
After your first success, you'll have to try again. You will fail again. But you will keep trying because you understand that success is an iterative process.
With each mistake, you must adapt to do better the next time.
Those who understand this will succeed sooner or later. Better yet, they maximize their chances of lasting success over time.
