They occur when many of those choices work for us.

And it is not required, not even possible, to avoid mistakes.

So to see any big success we need to continue taking action that is needed to succeed.

And not be bogged down by failure and mistakes enroute.

Big successes are also rarely linear. 

Something we do, may take us up and then another action, another choice can pull us down.

Key is that we never get out of sight then ultimate goals and take action to get out of a current trough.

So have a line of sight on the future, and focus on the present, on what is right ahead.

This is true of almost everything in life. Building a startup, nurturing a relationship, and creating a fit body.
