There is so much to do when starting a business but trust me when I say the list rarely gets shorter. Don't let this deter you from putting in the work because, little or much, it has to be done.
It is important to keep a to-do list but what's more important is to not allow yourself to become overwhelmed with said list. Work at a pace that is comfortable for you and beneficial to your company growth.
If you allow yourself to get burned out, there is a strong possibility that you may find yourself among the list of failed businesses. Remember, slow and steady wins the race but also maintains longevity.
