yes everybody has own predictions about the market but these predictions sometimes works usually when they are according to the exact information and data, most of the people are the good predictors who can predict the price of bitcoin that is because of their research and study which makes them perfect, so i think there is always a room for learning something new about the market and 'study' is its best solution.
It comes a time in which even if you still have a lot to learn from the markets you are not going to necessarily get better at predicting what it will do, you must always accept a degree of uncertainty from the markets, this will save you a lot of frustration, it is understandable to have a desire to predict the markets perfectly but that is just a dream, if you can tell 90% of the time what the market will do, and some strategies are able to do exactly that, then you have already reached the limits of what it can be accomplished with technical analysis.
