I would prefer to say that "failure COULD be the mother of invention."

It simply depends on the person's reaction to failure.

Do they get discouraged and give up, or do they learn from their mistakes and carry on towards their goal? 

Not always. 

It has happened to me that after a failure I get frustrated and I stop doing something because I do not find it rewarding and I feel it is not worth keeping on doing that because I won't be able to achieve a particular thing. 

Not always. Sometimes,  it's a mother of depression which in turn a mother of suicide.

Sorry.

the 99% of our time we are failuring...

your society included...

every society after a bit is considerated crewd of idiots... have understood nothing... and have believed in cracies..

we are born for failure...

this si the reason you don't start to walk without fall apart...

it's symbolic...

the most important things  is be modest...

know you condition like human..

don't forget never you are an idiot...

i totally agree with that cause failure means experiece 

and to be successful you should have alot of experience.
