Getting there fast and knowing how to stay there are two different skills.

Arriving somewhere and holding a position ask for different abilities, and talent only handles the first. Speed comes from energy, luck and a certain fearlessness; staying comes from habits, repair work and being pleasant to deal with over years. People who rise fast and then vanish rarely failed at climbing, they just never learned that the second part was a separate job. Nobody warns you about it.

If something went well for you lately, spend this week on upkeep instead of the next win. Fix what you have been ignoring, reply to whoever you owe, tidy the system.
