I think that mainly depends on when people consider themselves to have failed. If they try something and it doesn't work and they consider that a failure, then they may have hundreds of failures before they have a success. However, if they continue to try multiple possibilities for a solution and do not consider it a failure until they have all proven not to work, then the failures are much fewer. That said, every failure in life isn't really a failure if we learn something from it and thus have a better way to do things in the future. As with most things, it all has to do with mindset...some people are successful in everything they do and others are "born losers," yet these two types of people generally run into things that don't work at the same rate. If you don't want to consider yourself a failure, then simply keep trying and don't let every minor setback be considered a failure.
