The moments before it happens will be the moments we remember.
Proposing to a potential partner;
Responding to your boss' "we need to talk" message;
Every minute that leads up to a family gathering;
Seconds before you step on stage and wonder if you memorized your music enough (pro tip: you haven't); or
Waiting in the waiting room before a dental exam.
We remember the anxiety, the stress, the emotional effort, and everything besides how it felt to cross the threshold and do the thing.
If the lead-up is keeping you from doing the work you need to do, remember that you're exactly where you're supposed to be - and we're all counting on you.
