Stop placing all the blame on other people for how they interact with you. People treat you well/poorly based on how they perceive you. A lot of social behavior is cause and effect. Take responsibility for (accept) the fact that you are the only constant variable in your equation.
Start focusing on how you interact with the world. Record yourself speaking. Have a friend take video of you while you’re talking to people. Do you come off as aggressive or abrupt? Do you look shabby? Don’t take it personally if you do- take measures to correct it. This isn’t being fake, nor are you not being true to your self- this is being true to your best self. You don’t need expensive or trendy clothes- hygiene and dressing neat go a long way.
If you’re 20+ overweight- know that people dismiss you because of it. This is a reality I’ve dealt with since I was a kid. When i was lean, people treated me much better. It’s easier to interact with the world. Sacrifice the pie. It’s not about abs. It’s about taking care of yourself, discipline and enjoyment in moderation. But whatever you do, don’t blame anything on them. Take ownership of your actions, see what you messed up on, fix it, and move on. In life, you only have complete control over one variable- your actions. Take ownership of them.
Remember- these are notes to myself. Don’t take them personally.
