Its up to you..what you can do your level best..If you have ability to take responsibility then you will 100% success in freelancing work. You can also get many businesses as like small organization ONLY if you dedicated with your work and ofcourse responsible.
Let me give you an example. I was looking for a writer before 6months ago and I finally found from DP. He is from CA (I cant disclose his name here ). I can see him always available..One day, I told him when you take rest..He gave me amazing ans that I don't want to loose my clients as well as reputation so I always try to stay with them and about rest, I take whenever I get chance
I am still doing business with him and like his work as well as responsibility.
