Never waste time logging in again:

scp ~/.ssh/id_rsa.pub me@[IP address]:/home/me/.ssh/authorized_keys

Make aliases for your most common commands. Someone in a similar thread posted a script for parsing your history to find them out. For me they were all git subcommands.

Write a script the second time you have to do something.

On a macro level: Don't work on doomed projects. Don't update tools in the middle of a project unless the current version is a roadblock.
