should i grab it or not if the best things happened in a wrong time?

Well it depend on the situation if opportunity comes and there is such complication why not grab t. But if there is a problem along the way try your luck next Time.

First off: The best things in life are the ones that we worked hard for to achieve. If we did not work hard and smart for it, maybe it is not meant for us. I remember a quotation from the book "Millionaire's mind", it says "Be the right person in the right place at the right time." So i guess if a good thing in life will come to us in the bad time and there are no any option left, maybe it is wise to think about your accomplishment of how you accomplished this great thing. If it is meant for you to have it, then take it, it's yours. Best of luck and have a good day...
