Years ago, before I became a coach, I joined a newly created team in a corporate job.
Several of us were new. There was energy. Potential. A sense that something important was starting.
There was also complete confusion.
No one seemed entirely clear on who was meant to do what. Responsibilities were blurry. Expectations were fuzzy. We were all trying to find our footing while looking, at least on the surface, as though we knew exactly what we were doing.
I still remember one colleague saying to me, almost in passing:
“My coach taught me the first 90 days in the new job need to be SMART.”
At the time, I remember thinking: What does that even mean?
I learned the answer the hard way.
Because the first 90 days in a new job are not just important professionally. They matter deeply on a human level too.
Of course, when people land a new job, they are often excited. Relieved. Proud. Full of hope. And rightly so.
A new job can feel like a fresh start. A reward. A turning point.
But what many people underestimate is that starting a new job is not just an external transition.
It is an internal one too.
You are not only learning new systems, new people, and new expectations. You are also navigating uncertainty, visibility, pressure, identity shift, and the quiet desire to prove that the company made the right choice.
And if you do not enter that phase with enough awareness and self-leadership, the cost can be higher than people realise.
You may start overperforming before you have found your footing. You may say yes too much because you want to be seen as capable. You may hide your doubts and avoid asking the questions that would actually help you. You may adapt so much to the culture around you that you lose connection with your own judgment, values, and style. You may burn precious energy trying to prove yourself instead of using that energy to understand, build trust, and contribute wisely.
From the outside, it can all look very positive.
High effort. High commitment. High responsiveness.
But underneath, something else may be happening.
Stress may be building. Self-doubt may be growing. Old patterns may be getting activated. And the new beginning that was meant to feel expansive can start to feel heavy very quickly.
This is one of the reasons I care so much about this phase.
Because I have seen how easy it is for brilliant, experienced professionals to focus only on the external demands of a new job and neglect the inner work the transition is asking of them.
And that inner work matters.
It is the work of noticing your patterns under pressure. Of resisting the urge to overprove. Of staying curious instead of reactive. Of building trust without people-pleasing. Of being visible without performing. Of learning a new culture without abandoning yourself inside it.
This is self-leadership.
And without it, the consequences can be real.
You may damage your credibility by moving too fast. You may create confusion by trying to change things before fully understanding them. You may become exhausted from unsustainable effort. You may struggle to build the right relationships because you are too focused on doing rather than connecting. And sometimes, sadly, people can end up questioning a job that might have been right for them, when in fact what was missing was not capability, but support in navigating the transition well.
That is why I do not see the first 90 days as just a settling-in period.
I see them as a pattern-forming period.
A chapter in which the way you think, relate, communicate, pace yourself, and position yourself begins to shape what comes next.
Yes, there are practical things that matter enormously.
Observe before judging. Clarify expectations early and often. Take time to understand the culture. Build relationships intentionally. Stay out of politics until you understand the terrain. Resist premature changes. Keep a learning mindset, even if you are senior.
But underneath all that is something even more important:
Who are you being while all this is happening?
Are you leading yourself, or are you being led by pressure? Are you responding consciously, or reacting from old survival strategies? Are you building a sustainable foundation, or sprinting into a silent struggle?
Five years after that confusing beginning, helping people navigate the first months in a new job became one of my niches.
And one of the things I love most about this work is helping clients turn what could become a stressful proving ground into something much richer:
A time of grounding. A time of learning. A time of thoughtful visibility. A time of becoming more intentional about how they want to lead, contribute, and show up.
Because the first 90 days are not just about succeeding in the job.
They are about setting the tone for the chapter.
