The three best pieces of advice I learned in the last few years:
1. Ask for what you want and allow the person an opportunity to decide to give it to you or not. If they do not, you need to move on. You have free will and so do they.
2. If you have an idea of how something could be done better or different, offer it once and if the other person does not take it, let it go. Unless you are their boss and responsible for a mistake they make, let it go. Do not try to convince, cajole, persuade, demand, or otherwise try to get your way. It's a bad look and you are the only example of you that people see.
3. Stop talking.
I have to work on all of these all the time. I share in case they are helpful to anyone. Thankfully I just ran into the lady that lives in her car in the parking lot and she asked for my hand and prayed over me right there. It is tough out there, most of us have challenges with employment and money, including me. Some of us with our safety.
