Impressions of the writer of the first 3 letters

Initially he seems somewhat ambitious, as he speaks of what he wants to accomplish and the previous things he has done, but overall in the first letter he seems to be more interested in seeking an adventure to escape from the luxury he lives in than doing something serious. Furthermore the longer he is away, the more we get a strong impression that affection is very important to him and he longs for it. However he is clearly devoted to his cause, and puts everything behind this in order to succeed which would further imply he is ambitious. The final letter suggests impatience and the long for human company at a heightened level, also rather than being as floral and well written as the previous two, it is more hasty and uneasy. Overall, the writter has a clear longing for human company and affection, but perhaps his ambition prevents him from gaining this which suggests he is a restless character who must feel powerful in order to be fulfilled.
