You spend a lot of time learning spin then learn you don't need it
You spend a lot of time learning side spin along with controlling deflection and squirt, then learn you rarely need much side spin. Granted, the first shot after the break or after the other player's turn you may occasionally need a lot of spin on a longer shot but this is rare and you are almost always better off pocketing the ball and taking a harder second shot than using extreme spin on a long shot.
Angles are the secret to lazy man's, or in today's times lazy person's, pool. Angles modified with high or low or just a touch of side will do almost all of the work. When a shot is coming up where spin will be handy, make sure pocketing the ball itself is easy and in other than rotation games, the table is largely cleared. Whenever possible I try to avoid heavy side spin on shots with more than two feet between the cue ball and object ball and with the total distance from cue ball to pocket more than three feet. Angles makes this possible.
A lot of side spin and distance is dangerous for any player, thus the popularity of the low deflection cues which minimize the effects. As a player develops first they play a simple game. Then they complicate it. Then they make it simple again.
