Remember when you were younger, having a great time in the pool and suddenly the lifeguard blew a whistle and informed you and your friends that you needed to vacate the pool for a period of time and let the adults have their fun.
"Adult swim," would be announced and the pool would be reserved for just "grown ups."
Sometimes I think the very thing we hated as a child, becomes our security as an adult. We want someone to blow a whistle and tell us it's time to start working on our goals or our passions; time to move into a territory cleared of unpleasantries and offering a safe haven to make our passions happen. Like that whistle indicating adults were guaranteed of a less obstructive time in the water, thinking you will get an obvious indicator of that perfect time when you are meant to take a leap of faith is hoping for something that may never happen.
It's good to be cautious when treading into new territory, but often waiting for what you think is an indicator you can participate without unnecessary interference is futile. Maybe it doesn't seem like the perfect time for you to sample the waters or even just jump in and go for it but you might never get in the water waiting to hear that whistle and what good is a day at the pool without at least enjoying the refreshing opportunity to sample the water?
Maybe you will be fortunate and the whistle will blow, and all the things imperfect about where you are about to venture will be removed but if you refuse to wade in while the pool is a bit more crowded and noisy you might end up stranded waiting on the sideline missing a chance to perfect the strokes that could never be practiced without the water and missing an opportunity to seize the moment.
