“Success is walking from failure to failure with no loss of enthusiasm” – Winston Churchill. Failure demotivates, but nothing teaches as much as himself. When you take advantage of failure to learn, then you are progressing even if you don’t realize it.
“A goal is a dream with a deadline” – Napoleon Hill. This phrase hurts, but it is very real, there are dreams that cannot be achieved at certain ages, an example of this is almost all the genres of athletes that require youth and where they retire at a certain age limit for the most part.
