There will be some things that work and grow your business. There will be other things that won’t help your business grow. What you have to do is look at what is working right now.
If you repeat what is working, your business will continue to grow. If you like where your business is heading, keep on doing the things that are allowing your business to go so far. Keep on repeating what works because you will be able to have a thriving business.
While you repeat what is working, you can also experiment with your business. You will eventually find something else that works for your business just as well. Then you can alternate between various methods that work and allow your business to grow.
If it works, stay with it, because it will keep on working.
