Hello Iresa, I am new to the group and have been following manifestation for quite some time now. I have not really manifested anything big as of yet, but small things have worked for me.
My suggestion to you would be to manifest small, something you know can happen. Once you have found that small thing, you need to visualize that it has already happened and how your life has changed after that. Do this every day for a week and then forget about it.
