I'm north of 40 now, so while I both love and agree with your advice, I'd like to add a caveat. Even if you are lucky enough to be able to use an ORM for your entire career, you will still be well served by learning and truly understanding SQL.
In that sense, I'd argue that an ORM is only appropriate if your understanding of SQL and database design are strong enough that you can understand what's happening under the hood if/when everything goes to shit!! :)
