I've been actively investing for about 5 years now but have increasingly gotten into a mindset where my value as a person is entirely dependent on how well I've done in the market that day. I lost about 60% of my worth in the 2008 crash, clawed back so I was up 18% over the 2008-2011 period but have taken losses so I am now down 3-4% over the 2008-2012 period. I keep running my old trades through my head, calculating what my net worth would be if I'd avoided my worst trades, etc. This leads to self-loathing and a loss of self-confidence that contaminates other aspects of my life. Does anyone have any tactics for compartamentalizing stock market failures so you can continue to function outside trading hours?
