GMAT is not a difficult game, but the devil lies in the details - you need to train yourself to become mechanical (from the perspective of GMAT) and you need to understand the rules of the game to win the game. Easier said than done. This is a personal experience and open to discussion. So, take this as a starting point, and start thinking about your prep as you move along the process. Hope this short post helps.
During the beginning of my prep, I reached out to several people - some who had great GMAT scores, some GMATClub moderators, some experts- for help and each tried to respond to my queries. And all responses were similar - don't worry about time, with practice your time will improve. Nothing specific about the pitfalls, about what I should strive to achieve, the path and the hurdles that I can come across. With all due respect, this is a lazy suggestion. It's like telling someone struggling in a dark room to keep patting on the walls and eventually you will find the switch to the light. If you really want to guide someone - please take some time and provide suggestions that are more reflective and helps one connect the reasoning behind an approach and understand better what skill one should try to inculcate.
What I have learnt is that - GMAT is a non-creative constrained test of one and only one skill - finding inferences within the context of the provided scenario. All the practice that one does is to develop that skill. The skill of finding inferences. All the formulas you learn, all the patterns you try to recognise, all the rules, the idioms, the exceptions are for that one purpose - to be able to quickly and efficiently find inference points and related inferences. For Quant, you practice a lot of questions to make that process more mechanical and evidently, people are able to do that much easier in quant than in verbal. One reason for it is that quant is maths at the end of the day, so it's definite. Even if you don't get the reasoning, if you know the formulas and have developed the mechanical skill you can force yourself into getting a 50.
For Verbal, you practice more so that you can understand and compare your approach of finding an inference to that of the GMAT. That is the main reason why all the experts suggest - only follow GMAT Verbal Questions. Because it's their test so you need to understand their approach to drawing inferences. And they apparently spend tens of thousands of dollars to formulate those questions so, they ought to be strict about it.
Later, I found a video by

Invest some time, in thinking of how you are approaching your prep and whether you notice something that can help you streamline your prep and become a better GMAT test taker.
Good Luck and Stay Safe.
