Specific ambition and non-specific ambition look pretty similar on the surface, and it's easy to emulate the wrong one.

Specific ambition, combined with relentless execution, is extremely powerful.

Non-specific ambition leads to a lot of energy and random movement but no forward progress.

Specific ambition means having a very clear vision for where you plan to go, and perfect clarity about the next few steps.

Reading about history always seems to indicate that the cold reality of important work is about 1% glamorous plans and 99% unglamorous and very focused execution. (There are some occasional exceptions for scientists and a few other categories.)
