This is always important to remember if one is going to think clearly and carefully:
"When nonsense is spoken or written, or when something just seems fishy, we can sniff it out. The road out of confusion can be a long and difficult one, hence the need for constant attention to detail and particular examples rather than generalizations, which tend to be vague and therefore potentially misleading. The slower the route, the surer the safety at the end of it. That is why Wittgenstein said that in philosophy the winner is the one who finishes last."
Of course, balancing this wisdom against the necessary risk of truly living, especially living in faith - which requires that infamous 'leap', is the great challenge we all face!
