Don't do something because you are afraid of the consequences or afraid of exposure or afraid you're stepping too far out on a limb. Be sensible - don't throw all your money away on risky stocks, investing in your friend's latest invention or leave your job before you've replaced your income - but don't allow your fear control your actions either.
We should be afraid of real things such as automobile accidents, illnesses and diseases - but we shouldn't allow abstract fear to rule our lives.
Sometimes the thought of what COULD BE affects us more than WHAT IS.
Live in the RIGHT NOW and deal with the real-life things going on RIGHT NOW, but don't get caught up in the WHAT IFs and especially not the I WISHes (i.e, What if I lose my job and I Wish I had saved more money). Deal with what's in front of you, but don't get caught up in fear.
Let your dreams be your guide, but don't let fear take you out of the game.
