People will say no.
Something will not go according to plan.
Your efforts will go unnoticed.
But should that matter?
Because what happens when people actually say yes? When things finally go according to plan? When you ultimately get what you want? Will you be ready?
Here's the thing, you never know when that 1 time out of 10 will happen. So why not do what you need to do and do it well 10 times out of 10?
Because it's actually easier, yes, easier to do something 100% of the time than 90% of the time. You get into a groove and things just flow.
No more backtracking. No more procrastinating. No more analyzing. More doing. More acting. More doing it right the first time.
