Practice
Practice, Practice, Practice........ I only watched a little over 8 mins and what I see all through out the video is a guy who is a good shot maker but does not think at all about position, You took so many shots that you just hit hard and had no idea where that cue ball was going. Why re-rack after a miss? Keep going, there are a lot of balls on the table. Work out the rack. You finally got threw a rack, but ended up with poor position on the break shot. You did make the shot but had no energy going into the rack, getting stuck. Then you attempted some type of shot from the sky. Why not play safe when you get stuck like that, then start over with a re-rack? Teach yourself some defense along with offense. Here is something to challenge yourself. Don't shoot a shot unless you ask yourself: what ball am I trying to get the cue ball to for my next shot. Even if you do not make it to that spot, at least you attempted it. I hope you take all this well, it is meant to get you on the right track. Good Luck & keep practicing 14.1
