CA in practice or Stock Trader

Since I am restarting my CA again at the age of 29 after many years of depression..... I have this dilemma. I don't want my journey to be too long now for obvious reasons including marriage as well. I lack skills for a job and for practice (which may or may not work for me after Chartered Accountancy). So I need to learn stock trading to be one trader but after CA. How to start as a NOVICE. I got no clue. I hope someone will understand and reply soon.
