I agree with L.Nielsen's sentiment that you are «almost there» — close to realising that this is the only life you have and that all your effort should be directed at living it well for it's own sake, close to realising that you are strong enough
as an individual to face the world without the psychological
crutch you call god, close to realising that you are a good human being in your own right, close to realising that your own
successes, failures, loves and fears are yours and yours alone, not attibutable to an imaginary creator.
However, you don't want to use demo account trading
as a
crutch... trading a real account is different due to the real emotions involved, so just be sure you switch to real - money trading after you have achieved
success on demo... don't be afraid of trading real money, because eventually you will need to make the switch to real money trading.
