I think you should start by constructing a trading plan. First you need to find out what type of trader you are, look into things like your behavioral, emotional, and personality traits. Are you a patient person, risk averse, discipline etc.. You can determine, what types of time frames fit your personality. If you are not a patient person then longer tf's might not be for you and vice versa. Also look at different strategies and what appeals to you and fits in with your trading personality. Do not fight it, flow with it.
