Also, here is a favorite Kipling poem of Warren Buffett, the second one is the hardest for many. I have lost to that second a few times before with stocks, to sell when nothing has been happening for months with the sp only to see a spike over the next day, week or month.
If you can keep your head when all about you are losing theirs ... If you can wait and not be tired by waiting ... If you can think – and not make thoughts your aim ... If you can trust yourself when all men doubt you ... Yours is the Earth and everything that's in it.
