Not sure about this at all but what about practising mindfulness instead? I'm just starting to.
I am all for positive thinking, but I think you are setting yourself up for a big fall if you believe you control things like meeting a man by your thoughts; what I DO believe is that you can control your own personal emotions and feelings through your thought life and through speaking out positive rather than negative things. By this I mean that thinking negatively and then talking negatively makes you ..well...negative ...and you get into a negative cycle where the good stuff doesn't have a chance or where you're cutting off your own nose all of the time without realising it. For example if you are generally negative, you will be quite a draining person to be around and actually, a lot of guys will run a mile from that, you may miss out on jobs and opportunities because you're too down on yourself to go for it or jeopardise it whilst you're there, etc etc.
I had a friend in her 40s who always got the first and second date but never a third. She was a massively negative person, a real Eyeore...I get it, as she'd had bad experiences and I've had shit by the bucketload myself, but my theory is first date she tried very hard to be light, funny and positive and they loved being with her (she was amazing when like this, attractive and a 'catch' as so talented and clever) but on the second date she let it all hang out telling her story and they didn't actually want to go back for a third. Obviously a potential relationship gets to know the baggage at some stage but not straight away, and it's all about your own response to it too. I.e. XYZ happened, it's been awful, my life is awful, is this therapy or a date or XYZ happened and I've worked hard to get through it, I'm blessed with awesome friends, and it's onwards and upwards.
That's just my take on. I don't go for new age 'ask the universe' stuff but I do believe we have a huge amount of control over our lives by our own thought life, words, and reactions to the bad when it comes alone. You really can talk yourself into or out of most things.
