Once we keep our mind on something and follow up, we will surely achieve a desirable result we craved for, no matter how hard it might seems at first.
The impossibility could be made possible with a lot of effort putting in place and perseverance being our number one priority. But if we give up easily after an attempt or two, it will surely amount to time and scarce resources wasted without drastic and positive effort getting it in the right possible.
People often give up easily after an attempt has been made but this wouldn't really help getting the situation under control, I believe if we aren't failed for once in our attempt to make things happen, we might not be good enough or find it difficult to profer more adequate and lasting solution to the so called surfacing problem that might emanate for the fact that we dont fail to fall forward. Remember, fail and fall forward then failing to pull through difficult situation.
We shouldn't be scared to fail but ability to fall forward after an attempt has been made without desired result should be paramount in our life. I will say, if you never fail once, you might not get it right or never developed to extremely end result. I'm stressing failure here, I'm not talking about examination failure but rather insinuating on research or practical expect of vocation.
I like this popular saying, " success is not final and failure as we see is not the end of race and not really fatal but the courage to continue and fall forward is what matters and does count. Instead of seeing failure is a unrealistic setback rather see it as a stepping stone to success with the desire to learn from your someone mistake.
Overcoming failure in life require alot of commitment, determination and consistency, remember that fear of losing always bring about failure. Never be vulnerable so that fear won't set in. 
<Don't Quit
by John Greenleaf Whittier
When things go wrong as they sometimes will,
When the road you're trudging seems all up hill,
When the funds are low and the debts are high
And you want to smile, but you have to sigh,
When care is pressing you down a bit,
Rest, if you must, but don't quit.
Life is queer with its twists and turns,
As every one of us sometimes learns,
And many a failure turns about
When he might have won had he stuck it out.
Don’t give up though the pace seems slow,
You may succeed with another blow.
Success is failure turned inside out,
The silver tint of the clouds of doubt,
And you never can tell how close you are,
It may be near when it seems so far,
So stick to the fight when you're hardest hit.
It's when things seem worst that you must not quit.
For of all the sad words of tongue or pen,
The saddest are these: "It might have been.”/>
The phrase 'never give up' should be adopted by all soul that intended to excel and triumph. There is need forbearance and the end of it is resounding success.
