2. Keep in mind that most influencers, actors, athletes, and trainers have gained their physique through genetic luck, drugs, unhealthy eating, camera tricks, lack of balance in life, and extremely hard work guided by one-on-one coaching. It might take you 12 months to look muscular if you're a normal person doing a normal routine. Good strength routines will have you making regular small increases in resistance, so you will see constant small progress in strength on a daily/weekly/round basis from the beginning!
3. Spend a week tracking what you eat in an app like Cronometer. Those results will guide you on how best to modify your diet: the default macro/micronutrient targets in the app aren't a bad place to start. It's often recommended to increase protein and calorie intake above those targets if you're trying to put on lots of muscle.
Finally the sibling comment about goals is a great one. I'd suggest your #1 goal should be to not get injured, as injury will prevent you from achieving your other goals (and is very common when starting new sports/activities!)
