Well, the experts too say, not in a one go you can become expert of anything. You need face hardships and struggle. If you achieve anything without even trying what kind of life would it be?
How can you then define your life. When God gives you hardships, we even gives you the courage to face it. Yes sometimes we loose hope, but we stand up again. The journey of writing is same. You cannot say that if today i write well, without consistency, every time you'll write well. So just keep writing, bits by bits every day.
