Developing a business plan 2

Yesterday I was talk about Developing a business plan and I didn't finished it.So today I will continue talk about this.

Let's say some benefits of having a business plan:
It can make the entrepreneurs think carefully about their business so it's helps them make more changes to success.Also a good business may help the business attracts more investors therefore can make more finance. Also if you have a business plan you will have a good target ,that may encourage you to do better in your business.

But in the other hand to make a business plan also would have some problem:
Like if you make a over-focus plan or expect too high will make you feel less confidence .these may cause a business failed.

So I know to make a good business plan you must consider the real situation and the plan must fit the aims in your business. For a successful business a plan is very important.
