I’ve seen success get on top of people’s heads and I’ve also seen the same people spiraling down back to where they started.
Success should never swell you up, it is always a responsibility more than a reward. If you do good once, you’ll be expected to do good everytime and if you don’t do that, you fail.
You can probably get lucky to get success at something once but to retain that success is a bigger task. Those who can’t handle the momentary fame that comes with success are often the ones who end up losing their position.
The best way to retain your position is to stay humble. To just focus on what got you here and getting better at it. Success is only a result, and results should never influence actions.
