Never Put Anything Off

From Zanecorpwiki

The general idea is deal with everything immediately. For big, complex, slow problems, this may mean "start spending an hour a week wrapping your head around the issue". It always means boiling down to actionable items.

In financial terms, the most important aspect of this philosophy is to never incur a debt for which you have no concrete plan as to how you'll pay it off. The plan may be wrong, it may take a long time, you may miss some subtlety of analysis, but if you have no plan to begin with, then you have no chance.

The naive version of this idea, popularized by Dave Ramsey is: carry no debt. Debt itself is seen as an unmet obligation. However, that's true only if you don't have a plan. Taking on 5% interest to make an fairly safe investment at 15% with multiple back up plans to deal with failure is far more prudent than paying down a 5% mortgage so you're money can make sub-inflation returns in a bank account.
