One of the hardest things to do is measure success in anything and that goes for our purpose as well.
I believe the measure of success has to be earned over time. We have to realize that there will be failures well as successes.
The most important thing is to learn from both success and failures. They allow us to have a measuring stick in everything we do.
The most important thing is not to have our success at an unrealistic level. Over time we can raise the level of success.
When we begin working with someone we never should look at the full measure of success. Other words every step forward should be looked at success. A step backwards should only meant to be a little failure to look forward to the success ahead.
So success should never be really measured during the time with any one person.
Remember to that we were created for a purpose so success should be already built in though failures are part of life as well.
