Don't let your challenges make you fall below your target of living a better life, limit your challenges and you will soon see the end of the various options to stop trying to be at your best.
The word challenge isn't all that bad as a thing, it appears to be really bad to someone who is afraid to own up their place.
Lete take a look at some definitions.
Challenges is defined as...
"a call to someone to participate in a competitive situation or fight to decide who is superior in terms of ability or strength."
A situation that is glorified will become a glory up and above the ability a man will and should have to grow.
Limitations when gloried will put a paid to our ability to advance forward in life.
Don't limit your challenges, because the minute you do, you will never be above them.
Take charge and challenge the limits as they pop up and you will have a strong enough leg to stand firm when the earth threatens to pull you from under.
