can i start my own business..........?

Give me a better description of what you envision as your business. Do you want to have a shop or do you want to create new designs? Do you have any investment capital available? Any current debts? What country are you in?
Do you understand the basic laws and permits you need to open a business in your country?

You need to have many skills to be an effective business owner, and one of those skills is writing. Maybe you were rushed when you made this post, but ultimately you will need to be able to use correct spelling and punctuation in order for anyone to take your business seriously. While it's possible to run a small business without basic office skills, it much more difficult and implies weaknesses in other areas (such as accounting) which can be disastrous.

My guess is he's an ESL student. At least I hope that's the case.

In that case, I would say step #1 would be to create a business plan (in whatever language the banks need to see).

What are you selling? What do you DO?
repairs and maintenance? ideas and product development?
