It is not necessary, but having a coach or mentor, can be a huge benefit, depending on where you are, in your professional or personal life.
Coaches are not just for baseball, fitness, and sports.

What if you are further along your career?
Is coaching and mentorship still helpful?
Yes.
It might help you make the leap to a new level of achievement, open your eyes to a new opportunity perfect for where you are in life, or help you recharge, and find a new sense of purpose and fulfillment.
You don't have to leave this to luck.
A life coach can help you if you are stuck, or if you are unsure what should be your next step in your career, or life.
You only have to plug in "life coach" in the Google search bar, and names of life coaches will come up.

There are so many options to jump start an existing career, or a new career, in today's world.

Your very own private mentor and coach.
Never underestimate the value of turning to someone who knows you best.
When it comes to your job, or anything else in life.
