Success vs failure

Success is measured by many things. What do you or how do you measure success? Well lets use science! A. You have to account for variable and the many different options . B. You have to have a result you want to get to , or a hypothesis . what steps will get you you're desired result or a result ? C. Time and calculations: how do you calculate or track success?
Depends on the level of success you want and what goals you are measuring it by
Are you changing the goals as you go to accommodate for growth ? ( example : in sales you have a desired amount of sales you need to reach. You have a certain amount of steps or goals to get there. You measure by surveys or customer satisfaction. YOU can also track through referrals , spreadsheets etc. )
Failure : how do you explain , or examine failure ? The same way you measure success. With failure you feel defeated. You need to decide how long you will continue, when will you throw in the towel and give up altogether?
So measure success little by little and don't give up when one thing fails come up With a new perspective and continue to work towards success.
( example : for my business I keep measuring success by still receiving followers and likes everyday. I also measure by referrals and clients . ) once it get bigger ill measure by jobs and clients and once it gets bigger etc ill change as I grow and continue to measure the little successes everyday . )
