See this link for clarification.
It says to me simply...Look before you leap! Calm waters may look enticing but there may be things hidden in the deep. I think this applies to everything. Some peole...like me are all or nothing types and therefore are not likely to worry too much until it's too late what IS actually hiding in the deep. Jump in feet first and ask questions later.....not always wise.
Actually a very easy way to get hurt when you finally realize the people you jump in with were never really on the same page! It might have paid off to be a little more cautious!
And yet, it has always been the way I do things. I guess it won't change much any time soon!!
