I believe strongly in positive mental thoughts

People say what you can imagine you can achieve, but I think it is maybe more accurate to say what you imagine, believe and work towards you can achieve. Imagining having a mercedes or a hot wife or 10 Steem (lol) isn't going to magically happen. You have to imagine the specifics of what you want ( wife 3 years younger than you, 4 inches shorter than you what blonde hair, .68 hips to waist ratio, C Cups, skinny with a big ass and a bit of a tomboy in her hoobies but not appearance) believe it is true act, feel what it would feel like if it already had happened and then when the opportunity comes up to execute, you gotta execute.
