I think i've been a pretty unlucky kid. Got into the markets in October '07, and saw a 15% increase in my holdings pretty rapidly. Started to buy and sell (thinking I was it and a bit and going on rumours, ramps etc) and got burnt pretty badly. My losses for the year are about 2% of my income (which may not seem a lot) but that 2% is priceless to me in the lessons learnt!
If there is one thing that life teaches you, is that you never stop learning.
I am currently only turning a profit off 1 of my stocks (out of a total of 7). My losses range between 4% and 60% (wish I knew about stop losses!). Hopefully I can start to turn a profit next year (ableit a small one).
This site has been invaluable with all the technical skills learnt. I work full time and imagine trying to DT with Commsec & your boss walking past every 5minutes
One last thing I have learnt the hard way...sometimes the fundamentals are just not match for the technicals...
