Just for the record: I hear people use the term 110% all the time. I personally don’t believe there is more than 100%.
Here are two samples of trying to achieve big things and giving 100%:
In soccer you start by:
1) Try to prevent a goal
2) Try to score a goal
3) Try to win a game
4) Try to win the championship
In business you start by:
1) Try to make a sale
2) Delivery a quality product and or service
3) Have a record sales month
4) Have a record sales year
Now of course this is simplified and each step should be broken into more tasks in order to fulfill each, but both samples show it takes effort and increased effort to move from #1 to #5.
Something that may help is to create a written plan to execute from. Something to refer back to when distractions come up and something that breaks it down to little tasks when things get really busy.
If you have a plan and it isn’t working for you, maybe it needs to be revised or … maybe you need to focus.
