There are several grammatical errors in your paper and fixing them will certainly improve your essay. Looking at your first paragraph as our example, one of you biggest problems is using the wrong preposition.
For instance, in your phrase "ability in," in is a preposition that refers to location. For example, you can say "The cheese is in the fridge." In contrast, the preposition to is the preposition that indicates movement or action, as in the action of giving. So you really mean to say "the ability to give."
Another problem with your writing is that writers always need to create parallelism within the different clauses or phrases of their sentences. A writer creates parallelism by using the same verb tense and word order. For example, you have (or will have) "ability to give direction" in the first clause of your sentence, and can match that to your second phrase, after the comma, by changing it to "to control emotion." So you will create parallelism by changing your phrases between the commas to:
to give direction
to control emotion
to see in advance
to share strategies and
to influence others
Make these changes and each of your phrases will be exactly parallel.
Finally, another preposition you used wrongly in your first paragraph is as, in "as the attribute." The word as is a preposition that means like. What you really mean to say is "I consider 'effective leadership' to be the attribute...."
Following some of this advice should help you with editing the rest of this paper.
