Hi Nick. I want to check if my English sentences is correct. (6/4)

Maybe we can indicate when we went hiking EX

1. My husband and I went hiking last weekend. It didn’t take long to reach the top of the mountain because that mountain isn't very tall. In total, It took about one hour to reach the peak.
Seoul is usually very hot during the summer and this makes it difficult to go hiking. So I like to go hiking whenever I can.
2. Sometimes I prepare some classes or briefing sessions to increase customer satisfaction. As you may know, it's impossible to satisfy everyone and sometimes people will even express dissatisfaction. I try not to get frustrated when someone tells me they are unsatisfied. I always do my best to increase the average satisfaction level.

Hope you find this helpful. There weren't many mistakes but I did revise and even included some vocabulary. Best regards, Nick
