If I had to pick one way to simplify financial affairs, I would say consolidation of your accounts. Having multiple accounts, especially when they are at different banks, needlessly complicates things. For example, I have seen investors with four checking accounts and three savings accounts, all at different banks. This adds up to more statements, more tracking, more documentation and more stress. If an investor were not over the FDIC limit, I would question the need to have multiple accounts. My advice is that if you are under federal thresholds, think about combining your accounts to make life simpler.
