I'll be honest, I check my stocks almost everyday. But not the balance! I am mainly looking for dividend announcements and the occasional news of collapsing stock prices. (Fire Sales are FUN!)
If you feel the need to check your balance either
A. Your nervous and just want to see. Solution: Remember it always goes up in the end. Relax and don't worry.
B. Your new(er) and just want to see how high it will go! Solution: Either a dip/crash (in which case panic ensues.
HHGTTG time.) Or well, the newness wears off eventually.
C. You've made it a habit. Solution: Yea ok, this is where you just need to step away till the end of the month (or longer) cause your addicted!
D. You check similar areas, cause it's your Job so... it only a few minutes more to.... Solution: Stop. You know the direction of things cause, your job. Just remember yours is probably doing similar or better.
Balance is more then a number. It's a choice. If you need to step away do it, re-balance and come back with a smile! You already know what your doing, let it work for you!
