The coaching skills can be taught and learned. But we can't make somebody be a caring, alive, wonderful person. Coaches bring these qualities with them into the profession. There are many. You are working the clients who want to grow.
Most coaches do, at least at first.
If you already have a job, business or are doing consulting, we suggest you set aside one evening or day per week and fit clients in during that time. As you feel better about your coaching, you can expand your practice. There aren't many shoulds or can'ts in this business. It's very flexible, and you can design it to work best for you. We can put you in touch with coaches who do if you want to ask them about it.
