If you can just always do what is best for your business then you will have a better and wealthier life. Just do anything, just add anything, guard you business very well and try to grow it like a plant. Water it, give it sunlight, place it in a proper temperature. Do everything to make it stable and progressive.
Having a business is not that hard, it is not complicated. All you need to do is love it and do something for it everyday, make it your life, make it your bread and butter.
If you have a restaurant and you can't find ways how to make it better... just simply clean the table, make the place clean, add a new menu, force your workers to work and become friendlier to the customers and that's it... you already do what is best for your business. If you're business is declining and you need to cut expenses then just simply cut expenses because that is what's the best for your business, as simple as that. Just weather the storm, you already did what is the best, it is just a matter of waiting and being patient before the money enter your business again.
You can always think of something that will make your business better, you can always put in a very strong effort. Your business will only fail if you are not doing something for it. If you can still move and think of things then there is no reason to make excuses, you can make your business grow, you can make it powerful. Just adding simple things, just doing the smallest things that will make it better will help. Even if an effort looks like not helpful, if its intention is to make the business better then it is right.
