All you can do is all you can do. There is no more. Sorry, but you can’t give 110%. I know it’s a popular phrase, but it’s not possible. You only have 100% to do it. Maybe eventually you’ll increase your capacity so that what is your full effort today becomes more effortless in the future. But in terms of today, you can only try your best to do what you’re capable of.
You can only control what you can control – your effort and your attitude. Stop worrying about the future. Stop worrying about what other people will think. Stop worrying about the results. If you continue to follow the process, and it’s the right process, the results you desire usually come. It doesn’t always work out (there is no formula for guaranteed success), but if you think in bets and play the odds, you can put yourself in the best position to succeed.
All you can do is all you can do. The key to reducing stress is to let everything else go.
