A habit I picked up due to frequent computer system reinstalls (intentional and no): learn to be resilient to system failures. Know how to setup your system on a whim, and learn to forego too much pointless configuration, learn how to deal with doing the same takes on different OSes/distros.
I practise the same with email (and other coords): make sure changing them is easy, and do it occasionally to test if you've thought it through. Compartmentalize by having a number of adresses. You'll learn how to combine being lazy with being resilient, instead of just lazy and complacent. One email address at a company which you cannot hold accountable should not and in fact is not your identity. Prove to yourself it isn't and in that process learn how to deal with moving your identity (since that is how email is used nowadays).
