Start with this video for 'the subconscious mind'. Then get lost in all the related videos. https://www.youtube.com/watch?v=lw_Z401Bsb0 A book I highly recommend is Power of Your Subconscious Mind by Dr. Joseph Murphy. Also highly recommend Think and Grow Rich by Napoleon Hill. For staying calm, I got a lot of my practices from tinybuddha.com and zenhabits.com. Hope this helps!
