Barring special circumstances, the looks you are born with matter very little. What matters more is your presentation.
First, take care of your skin suit. It is the only one you own, it’s the one you have to wear, and it is the one everyone else interacts with. Hygiene. Grooming. Basic fitness. This doesn’t mean that you have to have a specific body type. This means that whatever body type you have, it has to be healthy. You can be heavy built and be fit and healthy. If you do not take care of yourself, why would some trust you to take care of them or their stuff?
Second, you have to prepare excessively. I always assume that I am not ready, so I over prep. Being prepared fills you with confidence. Being confident makes other comfortable and helps them trust you. There is no such thing as being too ready.
Third, keep your mouth shut and listen. Do not just hear…listen. This helps you better understand your situation, what others need, what to avoid, etc. When you do finally open your mouth, speak clearly, succinctly, and with confidence because you now know what is needed and you came prepared.
Bottom line is that, like all magic tricks, it is all about the prep work.
I realized that I was selling myself a story based on a fantasy. FDR and Kennedy sold us on a dream, but the truth is that the US is and has been ruthless, racist, and a bit fascist since its inception. With the exception of Obama (and even then it’s iffy), every administration since Carter has been very right-leaning and short of compassion (Clinton was basically a moderate Republican).
Looked at from that perspective, what gains we have made are something to be proud of. What stings is that some of those gains are going to roll back. Sisyphus something or other.
