Ambition is a lot easier to keep going when you like who you’re becoming.

Any long effort has to be paid for daily, and the quickest way to run out is to dislike the version of yourself the effort requires. If getting there means being short with people, cutting corners and never being present, the fuel runs dry even while the goal still looks good. Liking the process is not softness. It is what makes a long project survivable.

Look at the habits this ambition is building in you and ask whether you would want them in five years. If one of them is bad, change the method rather than the goal. Check with somebody close to you, who can see it more clearly.
