I presume this is a request. I am not interested in being a mentor, you can pay your 5K for a mentor program if you wish, but I dont mind sharing what I know and have learned over the years. This is realy a filtering proccess, taking in all the information I can handle and looking for a common ground, as well as looking for the sweet spot between profit and effort.
As to your dilema, typical situation, been there, done that. Devise a system to get in and back out before you take a leap. Do not think too hard about this, KISS, keep it stupidly simple. Price is the key, thats where you make your money. Price crosses over a line, in the direction of the
trend 
, confirmed by an oscillator. Thats about as simple as it gets, and it works well within the realm of your own judgement to make the final descision.
Once you have a system to work you need a plan,
money management 
, how your going to allocate your money and how much your going to risk on each trade, trade managment, how your going to manage a stop and handle risk and profits, scheduling, what time frames your going to trade and what hours your going to work. If you set yourself limits, the hours your going to work and the time frames your going to concentrate on, and how much your willing to win or lose before you take a break for the day, (presuming your day trading), that should help contol the urge to overtrade.
Also dont only day trade.
Short 
term trades, day trades, are often great entries into longer term trends, and holding a
trend 
is also a good way to minimize overtrading and learn how to manage a trade in profit.
Thats all for now, there are tons of books and courses out there, half of this business is reading and constant study.
