I’ve been knocked out a few times , but I have no idea how many concussions I’ve ever had.

It’s not about whether you get knocked down, it’s about whether you get back up.

Standing in the middle of the road is very dangerous; you get knocked down by the traffic from both sides.

Opportunity may knock only once but temptation leans on the door bell.

Trouble knocked at the door, but hearing laughter, hurried away.

If you get knocked down setbacks in life, like applying for a job if they don’t hire you  keep trying, keep getting up, keep doing it.
