Stop comparing yourself to others. Instead, compare yourself to where you were 1-2 years ago. Whether it's fitness or finance, use that as motivation for your own goals.
Always be the person who tells someone they have something in their teeth, shoes untied, fly is down, etc.

If somebody comes to your door selling a home security system and asks if you have one, always say yes.
If they ask which company, tell them it's none of their business.

Pay Attention to the smell of your home when you come back from a trip - that's what it smells like to guests all the time, you just get used to it.
Dont worry about something embarresing you said or did in the past. Nobody thinks about it as much as you do until you mention it.
Always say goodnight to your SO, even if you're upset with them.

Follow the 2-minute rule. If it only takes 2 minutes to do, just do it.
If you're a big procrastinator, this is a great and easy way to start fixing that problem. If it's something like taking out the trash, folding some clothes, or putting the dishes away, do them right there and then and don't put it off. If it only takes 2 minutes, get it out of the way!
