Life sure gives us serious lessons but I refuse to sit down and take notes. I can pretty well do that walking.
Why wait, till tomorrow when you know; it can be done today? If it can be done today, why not do it now? Why sitting down to take lessons, when you know you can still do that without problem whilst walking? Have you ever pondered about the saying " Time is money"? If Bill gates, Mark Zuckerberg and some others can make money every seconds, then why will you just sit down, and not make use of your time for something beneficiary to you and others? Don't waste that precious gift God gave you. It's never too late until it's too late.
