The world is full with emails that lay out brilliant plans.
And it is full (though admittedly less so) with excited replies to those emails, expressing a convinced “I am in!”.
But the difference is in what comes after that.
Some people are excited by the process of getting things done, bringing the team together, convincing the skeptics, repeating the details over and over again, changing their minds, changing other people’s minds, navigating the ups and downs, waking up to failure, presenting in front of a crowd, putting in the work.
Some people are excited by the idea and see all of the above as an insurmountable obstacle.
You are probably part of one group or the other depending on circumstances. Just be aware that it is a choice you can make, an attitude you can change.
