@HighIQ, I will address various statements in your post individually.

1) Not solving Codeforces problems does NOT preclude giftedness.
Previous answers to your posts/threads/questions on IQ scores and IQ tests have shared with you that the same IQ score does not necessarily look the same on various people: scores across the various subtests are rarely even, but instead show both strengths and weaknesses. People can both be gifted AND have a learning difference or learning disability. This is called twice-exceptional or 2e.

2) Having a low-IQ does NOT make a person a loser. Please be aware that labeling low-IQ people as losers is a very offensive statement. ALL persons deserve to be treated with dignity. IMO, the only way to be a loser is to treat others unethically (for example, by not following the golden rule).

3) It does NOT matter whether your brain is mediocre at critical thinking. You have written budgets and schedules to support goals... you also have it in your power to change the budgets, schedules, goals.

4) No one needs to be "impressed" with you, me, or anyone else. Consider awarding yourself internal, intrinsic rewards by doing what you enjoy and enjoying what you do, rather than craving external rewards. For example: following through and completing even simple tasks on a daily to-do list can sharpen skills, lend perspective, and increase appreciation, including self-appreciation.

IDEAS:
- You have previously expressed an interest in resuming college courses during the Summer semester. Might you begin now to study ahead, in order to alleviate some pressure on yourself during the summer semester?
- You have previously expressed an interest in lexile levels or reading levels of books. Might you begin to gauge the reading level of some books you like, whose reading level is unknown? Although the specific formula developed/used by some organizations may be proprietary, reading level ranges and readability index which I am familiar with are determined by some combination of: words per sentence, syllables per word, syllables per sentence. Individuals can assess reading levels of materials using online tools. Assessing the reading level of a number of books, could be a goal which one sets for themselves in working toward achieving a portion of the requirements in earning the Congressional Award for youth (for which the cutoff is the individual's 24th birthday).
