I'm always late for everything and I don't see what the fuss is about. FYI I'm a software engineer, in India. In software, there is a concept of a buffer period, which people learn to add to the estimates, because inevitably, things gets delayed. Maybe you need to recognize when to do this with people.

I don't know if you're some big shot CEO or someone for whom a few minutes is a loss in millions. I don't believe in living life being so worried about my time or others time. The only waste of time is doing a job and not hacking on something great. Here's a nice poem for you to sit back, take a deep breath and read.

LEISURE

What is the life, full of care we have no time to stand and stare. no time to stand beneath the boughs and stare as long as sheep or cows. No time to see, when woods we pass, where squirrels hide their nuts in grass. No time to see, in broad daylight, stream full of stars, like skies at night. No time to turn at beauty's glance, and watch her feet, how they can dance. No time to wait till her mouth can Enrich that smile her eyes began. A poor life this if, full of care, we have no time to stand and stare.
