Well... My approach was to just push through and eventually after a year have to quit due to a burnout. I do not recommend this strategy
If you like your job and it is worth it for you to find strategies, then I would say what others said before.
However, think if you really want to keep doing this job, if it is worth the exhaustion that comes with it, or if you might not be better off finding a different job.
In my case it was not just the extrovert nature of the job, it was also the cold calling (I hate calling on the phone, and I have some mild social anxiety. Not the best combo for a cold calling job), having to deal with constant pressure. Not just deadlines to get things done that are within your power to do, but also deadlines for sales, which are not in your control.
Added to that the fact that the entire office would applaud when you do make a sale, and I HATE being the center of attention.... yeah, not my job at all.
