Punctuality can be simplified to:
Step 1) Show up. Step 2) Show up on time. Step 3) Show up on time, ready to work.
It’s really that simple. If people notice that if you schedule a meeting with them or tell them a project will be done by a certain time, and it is done by that time they respect you more and respect your time more. However, if you arrive late to meetings and don’t finish projects in the time frame you provided, you lose credibility.
Just be punctual with everything you do. This is something I’ve been really focused on over the past year and a half and I’m noticing that people are starting to treat my time with the respect that I’ve wanted 🙂
