Comfort Zone? ( Kinda Long)

[Hybrid_11]

Its late here and my minds been racing due to the beginning of another month, i can not sleep so i decided i would explain my thougts here and hope to get some knowledge

I have been 8 tabling 2/4 the past 2 months with good success. The exact amount is irrelevant to the topic. I have to travel back in time before i can get to the topic tho

I am going to go back 3 to 4 months ago when i took my first dab into 3/6. I had the sufficient roll on empire poker from playing 2/4 so i decided to commit a month to 3/6 to see how i do at the next step.
I ended the month up about 1300 dollars which is not bad at all but over 33k hands it only gave me a .5BB/100 which is not to good. I decided the next month i would stick with 3/6 to see what i can do and took a bad month and ended up losing at 3/6.

The next month I began back at 2/4 but opened up an account with another skin and split my roll so that i could 8 table 2/4 instead since i could provide enough BB on each account to be safe there. I had a great month and did very well 8 tabling 2/4. So much so at times i decided to reattempt some 3/6 now and again but 3/6 was in the red by the end of the month for the few sessions i played. The month i was still up but 3/6 was no help.

This month i decided to focus solely on 2/4 and nothing else and sure enough i had a great month 8 tabling. Now im on the breech of a new month and am preparing to have another month of 8 tabling 2/4 but im kind of bothered by this.

I feel very comfortable 8 tabling 2/4 i have no worrys the swings dont bother me and i can be very successful. I have fallen into a comfort zone, nothing really scares me at this limit. There in lies my problem. This comfort zone has my mind stuck into wanting to just stick with whats easy but the other part of me wants to progress as most poker players im sure would like to do. 3/6 is obviously the next step but i just keep looking back at my earlier results and im just a little worried. The fear of 3/6 is keeping me away as i have none at 2/4. I would like to progress but just cant get myself to commit

Im curious if anyone has any knowledge or advice that might help me in getting out of this comfort zone and trying to reestablish it one step higher if people have had a situation like this themselves.
