work on technique and strength.
This isn't done by going to a max or a PR everyday. In competitive weightlifting it's well known that you develop quality lifting (technique and strength) by doing a lot of volume with 75-85% of your 1RM. Yes it's important to use heavier weights than that, but most of your work should be spent in the 75-85% range for sets of 3 reps.
Being in the right place at the right time is necessary to allow more weight to be lifted. Much time needs to be spent with light to no load in the best position for the job. This will develop flexibility, postural strength, muscle memory, and proper timing. You need strength to pull the bar, but rate, direction of force, and proper timing to get it where you want it to go. The greater the load, the greater the demand on the neurological components of the movement. Spend time in practice, not just in heavy lifting. There is more to be gained in being in the right position at the right time than in continuing to go up in weight with poor mechanics. This is just continuing to practice poor form. You will get better at what you practice. If that is poor form, then your poor form will continue to grow and will continue to inhibit your gains.
