Notes

Even he think you're smarter than others, with his little analyzing, and your sister always looked up to you, also when she needs help, and you're wasting your potential.
You're clearly smart, not the smartest person on earth, but smart enough, and you have being doing anything with that potential when you could achieve pretty decent things, or at least produce decent money, since you have no debt, and are smart enough to keep your finantials, still you have probably disappointed everyone, and still they trust you and think you do are smart, so you need to achieve those hopes and do good, is not hard, is just of working, being decent, being good at your job and having decent self-steem to produce results, and also having a goal of being a good worker, being conscious about it, and doing the best you can with your potential, but actually using it, focusing and fulfill it, with the best you can do by yourself and the best you can do of the world with all the help you can get, just it. Don't disappoint your family, all of it, because they're the one who matters and yourself.
