You can use the slower growth periods to prepare for the fast growth periods. Whenever you experience a period of fast growth, you will have to adapt to the new skill sets and behaviors required for your new role / responsibility. If you experience the period of fast growth and significant new responsibility before you’re ready, you may be “over your skis” — you may not have the requisite domain knowledge, leadership skills, etc. to be successful with that new responsibility. So use your periods of slower growth to build the skills necessary to be ready for the next period of fast growth. Think of the slow periods as the practice you’re doing to get ready for the “big meet” — the fast growth period.
