Yeet

I just recently started watching Leo's videos and I've decided I want to improve myself in any way possible. So I decided to start off by doing the practice known as "visualization", now since I'm new to all this stuff I'm struggling a bit and I don't know if I'm doing the practice correctly and I struggle to see images in my head I can barely visualize my own mother does anybody know how I can improve my visualation skills and how I can tell if I'm doing the practice correctly? Thanks.

Ok so I recently watched Leo's video on how to be funny it is a great video but I've encountered two problems. first problem is that I struggle to visualize second problem is that he says in the video visualize yourself seeing funny stuff everywhere and being a rascal but how exactly do I visualize myself seeing funny everywhere and being a rascal I'm struggling and if someone could help me out I would appreciate it.
