Jacob's Phenomenon

The Jacob's Phenomenon describes the tendency to perform worse on a second attempt at a task, despite expectations of improvement. This effect can be attributed to overthinking, reduced adrenaline and focus, or pressure to replicate initial success. Neurological fatigue and natural variability in performance also play a role. For instance, a basketball player may sink a perfect shot on their first try but miss the next due to overanalyzing their form. While the phenomenon can be discouraging, it is typically short-lived, and consistent practice helps individuals overcome the dip and achieve steady improvement.

Jacob

Two-faced like a Poundland Batman villain and folds faster than a Primark deckchair after two drinks. Cannot handle booze, cannot handle drugs, cannot even handle himself — but will still swear blind he’s “fine” while single-handedly ruining the vibe like it’s his full-time job.
Tragically, beneath all the chaos, there’s actually a decent lad buried somewhere… but he’s held hostage by Drunk Goblin Jacob.
“Whose idea was it to let Jacob drink again? I’m not paying for another fire extinguisher.”

Jacob

A VERY cute guy who is INSANELY intelligent, funny, somewhat outgoing and has an amazing personality, he also is a shy person until you get to know him, but he also has those days where he is the most outgoing person you’ll know. Jacob has an amazing body because he was somewhat chubby and insecure about his body as a teenager, has the most amazing eyes EVERRR!!! He is very dedicated once he puts his mind on something, he has HUGE dreams for his career. He is selfish, but he is unselfish about the peeps who he loves and is friends with. Has went through a lot as a child. Has a somewhat crazy side as well. He is also freaky....;))

EMILY: OML that’s Jacob, he’s such an amazing guy!!

Jacob

Jacob is extremely charming to anyone who’s meeting him for the first time. A Jacob is a great person to joke around with and knows how to make you feel special. His true intentions are always good but he may appear somewhat cocky at times. He’s inwardly caring and he loves his mom. He is very athletic and attractive. He has a tendency to push real things away but you’ll stay up late thinking about him anyways. Don’t mess with him or his girl or you’ll regret it. He’s so smart but doesn’t want people to know. His smile makes your heart melt and all the girls want him. He wants to come off as cool, and he is. He’s actually really romantic and caring, even if he doesn’t want to admit it. He’s really good at giving cute nicknames too. He’s pretty irresistible and although he has his rough patches, you won’t regret being close to him; even if your not with him forever.
Me: Hey, your hair looks good today.
Jacob: Thanks. You don’t look too bad yourself *winks and smiles*
