I'm getting better with this each day but visualisation always felt like work and was a struggle for me to begin with, I love learning new things from all aspects from life, so I'm forever searching for good things to read. This applies to LOA especially lately, I stumbled across this link a while ago and it just came to mind again so I thought I'd share it here for anybody who's struggling a little bit.
