There are some decisions that have to be taken at various stages of our life, fairly critical one's. There may or may not be sufficient time to analyze.
For me, instincts take over the control and there are a few signals that let me decide my action points...and when it does, it glows bright. Those decisions could just change the entire scenario, opening up a gate that could lead us to a world of opportunities or a dead end!
I have personally known people who have taken such decisions...they may be shaking hands with lady luck or still struggling to surface up, but one thing is for sure, there are a plenty of lessons to be taken to the grave.
