I used to set dates on important anniversaries of my life, but I think setting dates is bad tbqh.
Most people I know who've made it have been trying it consistently over like days, months or years. I feel like with any method you need practice or something, and setting a date creates this huge burden like everytime I was doing anything on one of my set days id be like "Oh its the last time Ill do x,y and z". Plus if Im specific about a method, and I want to do that specific one, then it will take practice to get it right. From everything down to the actual act to the survival instinct.
Now I just try it every night. I feel like I get a little closer everytime, and it just makes me want to do it more. Had I set a date Id be upset and disapointed that I missed it.
