Let me reflect on this mate and by saying,a world or life without challenges is not yet a completeife,come to think of it what will form our success story if no challenges as occurred during the struggle times.
Learn from mistakes, and start over...
Mistakes to me too are for humans,even though I don't subscribe to the fact that we should keep making mistakes too in life,but of all it is a way of helping us to do that which we are not perfect on with perfection later
