Repeat a mantra in your head. The mantra could be anything really. You do not need imagery to meditate. Another trick is to look at your hand and try to feel/sense the inside of your hand, focus on that.
I am on the other end of the phantasia spectrum; I have hyperphantasia. This causes problems with meditation because my ADHD gives me intrusive imagery.
The key with meditation is to just keep trying. Mediation is an incredibly useful tool but it is something you have to constantly practice. It is harder for people with ADHD to accomplish consistently but it is entirely possible to learn to do it well. If you practice enough you may learn how to live most of your life while meditating.
Learning how to meditate was the turning point to gaining control of my life and start on the road to a functional life. I am not saying medication (I’m on Vyvanse) and therapy (once a week for me) aren’t equally important or weren’t major contributors to better understanding and living with my condition but learning how to meditate and doing it consistently was when things started to click for me.
I am with you here. I have a 2003 BMW Z4, not as expensive as people expect it to be, fun to drive and have had very few problems with it. 114k miles on it.
Though I have not had to do any major fixes on it I do sleep better at night knowing that I have several friends who are car guys that have all the equipment and tools to pretty much fix anything on it, within reason.
Also, lots of enthusiasts for those cars out there, plenty of forums with 20+ years worth of documentation from people fixing their own roadster and helping others fix theirs. Small car, physical buttons and controls, well engineered, fast, fun and reliable.
