• update ID so you have longer before it expires
• P.O. box. I recommend looking for a company that provides the service instead of the post office itself.
• external battery for charging devices
• library card (usually require address so before is better)
• gym membership for showering
• work nights in the winter and day during summer. Change jobs if you have to.
• get a laptop, even if it’s too garbage to use or even broken. You’ll get kicked out of a lot less places if you’re pretending to work.

If have a car…

• if your car is long enough try to get a camping cot that you can lay out in the car. They make various custom ones that level things out for sleeping.
• Reflectix you cut out in the shape of your windows. Will keep your car cooler in the summer and warmer in the winter for you or your stuff. Also blocks view so less likely to have theft issues
