If there's a golden rule, it's this one, so I put it first. All the other rules are more or less elaborations of this rule #1.
You already know that you will never be done learning. But most people "learn in private", and lurk. They consume content without creating any themselves. Again, that's fine, but we're here to talk about being in the top quintile. What you do here is to have a habit of creating learning exhaust. Write blogs and tutorials and cheatsheets. Speak at meetups and conferences. Ask and answer things on Stackoverflow or Reddit. (Avoid the walled gardens like Slack and Discourse, they're not public). Make Youtube videos

A common mistake is cloning using the default (HTTPS) instead of SSH. You can correct this by going to your repository, clicking the ssh button left to the URL field and updating the URL of your origin remote like this:
git remote set-url origin [email protected]:username/repo.git
See http://stackoverflow.com/questions/7773181/git-keeps-prompting-me-for-password, make sure you are cloning your repos using ssh:
ssh://[email protected]/username/repo.git
Generally, you will add a git remote for your Heroku app during the Heroku app creation process, i.e. heroku create. However, if you are working on an existing app and want to add git remotes to enable manual deploys, the following commands may be useful.
Note that on Heroku, you must always use master as the destination branch on the remote. If you want to deploy a different branch, you can use the syntax local_branch:destination_branch seen below (in this example, we push the local staging branch to the master branch on heroku.
$ git remote add staging https://git.heroku.com/staging-app.git
