Fun story my biology professor just told us: When he was 23 he was married to his wife and worked two jobs to support them since she was in college: gas station attendant and construction worker. He worked these two jobs because that was the only work he could get since he was at the reading level of a third grader.
One night he was writing something and his wife noticed he was writing from right to left. Since she was studying occupational therapy she realized he had a learning disability and started working with him. He slowly began to learn to read, and at 26 got his GED and went to college.
His first year of college he took the lowest level math course he could take, 001. Over the years he worked on learning what he needed to, ended up graduating with a biology degree. He then went on to get his masters and PhD, graduating at the top of his class. He is now an extremely accomplished biologist and professor.
So don’t let anyone tell you that you’re future is based on your choices as a teenager.
