No.no.no
Besides, if you are trading your account, there are many times that you don't have a gut to trade using 6 to 10 lots per trade, assuming you are using 15-lot TST account. For TST account, you probably won't think of it the same way. Assuming your setups are reliable, you make over 10 Gs easily and very quickly in just few days by using 8 lots before something unexpected happen that will blow up your TST account. So, the bottom line is yes, it worth it. Period.
P.S. if you are a 1 or 2 lots trader and you are still struggling with trading, then you might not understand or feel the same way like I do and so, forget what I write in above.
