Some excellent advice here, particularly #1.
I pay a lot of attention to the investment process. In that regard, every investor — personal or professional — ought to have a clear investment plan based upon appropriate personal considerations, goals and outlooks and every investor ought to stick to that plan unless and until something significant changes. But there is a crucial component of the investment process that gets surprisingly little attention: our investment default settings. We can use them when we aren’t sure what to do, when we’re deciding what to do, when our circumstances have changed but our plan hasn’t (yet), or when we’re just starting out.
