It is important you take some time out of your schedule to work on your business projects. This could be either acquiring new skills, or implementing new ideas, or creating new services/products or just to simply stay up to date in your industry.
Some business owners may avoid this because they know it takes time and they are already too busy with their clients and day-to-day operations.
Something that helped me find that time is to treat my business like my own client. Meaning, I set a time aside throughout the week (an appointment for my own business). I will then focus on only projects for my business. This helps me improve my services and creates more opportunities. Simply put, treating your business like a client is necessary for your business growth!
