The best advice I got from my dad? Wear a condom.
If you don't have time for the small things, you won't have time for the big things
If you run a business, put on top your employees, then your consumers, and then your shareholders.
To be a great leader, you must be a great listener
You've got one go in life, so make the most of it.
Have passion for what you do; believe in yourself and your product and your customer; persevere; delegate; listen. Have fun. Today, I add: "Do good".
