Lots of good responses. Thanks all.
I think one reason I tinker more than I would prefer is that learning about and executing investments on my road to ER has become a hobby. I study it the way I have researched and studied other hobbies.
I haven't really hurt myself but I am guilty of unnecessary fidgeting with this fund or that ETF.
As an example when I first moved money to the self directed brokerage account a few years ago, I went with about 1/3 VWIAX, 1/3 VOOG and 1/3 VGT. It did well but I got nervous about over exposure to the tech sector.
Then I moved VGT to VTI which isnt 1 to 1 with VOOG but there is a lot of redundancy. Since then I have at times had VOOG, VBIAX, VTI, LMT, WWE, VWIAX, VWELX, BIV, and Core 401K Stable Value, or 401k S&P 500. Not all at once but I have been in and out of a few of them more than once.
Currently I am at a 62/38 thru a combination of VWENX, VTI, BIV and Core 401k Stable Value. This mix may not be optimal but there is a reason for each. I have VWENX because if a bear market is on the horizon I trust the Wellington management group will know how to navigate it better than me. I have VTI because I do agree with owning a broad swath of the US market in a blend rather than purely growth or value lean. I have BIV and Stable value because those funds are earmarked for distributoions over the next 4 years. Of these four BIV is the one I am mulling over.
At some point I need to become comfortable with my choices and consider getting a new hobby, and start treating this more like business....not work but business. [emoji3]
