Quote from Butterball:
To an extent I agree with the above. A good trader needs to detach themselves from the fluctuations of the current account value.
The less making money is on ones mind (to pay recurring and everyday expenses) and the more one can focus on executing the trading plan perfectly and as a result the better the performance should be over time.
IMO anybody who hopes to barely accumulate enough capital so he can grind out a bare living will have a hard time, since one will be tempted to abandon their plan in order to make ends meet more often than not.
To the OP: take your minimal required capital to quit your job and then multiply that by 3-5. That will yield a more realistic number that will allow for inevitable drawdowns and unplanned personal expenses.
When you start trading real money, be sure to reread the "Market Wizard" books and "Reminiscences" about once a year, for 5+ years. As your experience grows you will keep on finding new gems in the interviews that you previously overlooked.
I don't plan on quitting my job for as long as it takes me to become proficient and profitable in trading.
And yes, I guess you can call trading more of a hobby than a career (at this point). But once I learn the ropes, I'd like to turn this hobby into a career.
As long as I don't quit my job, money won't be an issue.
