Failure is all part of life experiences,even the richest man on earth today may have experienced failures in one time or the other but the reasons they made it to the top today is there determination never to give up and consistency to achieve greatness after some several failures were recorded.its up to you never to be weighed down by failures always determine and remain focused that one day your trials and errors strategies will pay off.
Failure is not only about money though. So even those who are rich now, can still experience a failure from time to time. If we are talking about money, most rich were actually born rich already or they have a rich parent/ancestors. They still have struggles in life and yeah, the reason they overcome it and be more successful is because of determination and other positive traits you mentioned there.
Failures are moving in a downward position, so it is only normal for us to be weighed or dragged down by them. This is where we can lose our balance or focus but a good rest for a while can make our head clear and give us a good positive energy to try again and work towards our goals in life.
