Going to the job site and not knowing what type of job you have that day. Some days it would be demoing houses, tasing out drywalls, insulation, or it could be a water job with mold. Everyday was different.
What I wish was different
There really isn't anything that I would change about the job, my coworkers and boss made each day enjoyable.
Advice
Keep an open mind about everything because you never know what type of situation you can get yourself into.
