Anybody who knows me knows that I try to be as nice and polite of a person as possible. Very rarely do I do stuff to hurt people, and even if I do, it's unintentional and I apologize for it. I am good at listening to people when they have problems and just need to rant, though I'm not great at the whole advice thing so I think it often seems like I'm not listening even though I am, just because I don't respond in fear of saying the wrong thing. I guess that counts as a strength and a weakness.
One of the more important strengths that I possess is that I am an extremely loyal and hard worker, and all of my previous employers and even my teachers can vouch for me. When I have a job, I am never late for work, I don't take off scheduled shifts unless there are some really extenuating circumstances, and I never leave until I know all my tasks are done, usually after double or triple checking (something most people don't tend to do).
One weakness I guess you could say is that I'm a bit of a pacifist. Conflict makes me uncomfortable, and as a result, I often say the wrong things or say things that I later regret because I don't know how to properly deal with it. Many people here, I'm sure, have witnessed that, as have many of my close friends IRL. It's gotten me into trouble many times.
Also I'm a massive procrastinator. I'm the type of person who leaves projects to the last minute, and even though they usually turn out really well, I'm generally unhappy with the end results, even if many people say otherwise. I'm also extremely modest, to the point where whenever people say nice things about me or tell me I'm good at something, though I may not say anything about it, I almost always think of people who are better. For example, whenever someone tells me I'm good at music, my brain only hears the mistakes I made and the people that sounded good, not the parts of mine that sounded good. Also, people often tell me I'm good at something and I'll tell them they're overreacting, or point out people who are better, or something else. My self esteem is very low, and has been for as long as I can remember. It's a huge weakness of mine, one that people have actually taken advantage of before.
