Could you please fix my sentences.
First, it made me stronger to face hardships because it was not easy to ascend the step slope of a mountain .Since it required lots of strength and endurance to reach the summit of a mountain despite the difficulties. Shall I omit despite of difficulties?
Thank you so much.
I would omit it. Seems a bit redundant. If you keep it, say "despite the difficulties."
The slope is "steep," not "step."
You need to make this into one sentence, not two. Or finish the thought begun with the "since." Your "sentence" starting with "since" is a fragment, not a sentence.
