Oh yeah, so many times I measured once then had to break something because I measured wrong. Lol. Also in respect of finance and other such decisions...rash action isn't often good.
If a wolf chases us in the forest, we run away immediately.
I stand and fight until the run-awayers are safe and then decide from there...the wolf sometimes needs a good fucking up and I have on occasions handed it out. (I get what you mean though.)
Seriously though, it's really important to be comfortable and confident in financial decisions and that comes through having the right advisors, doing the research and standing back to consider things from a little distance rather than when right up next to them...and sometimes that takes time. It doesn't always mean success will follow, but it puts one in a better position.
